Subject: Serious Concerns Regarding the Phone Number 0850 532 10 42, the Company “Nethas” and Possible Misuse of Meta‑Related Data – Request for Clarification and InvestigationDear Meta team,According to information available from open sources and user complaints, the phone number 0850 532 10 42 does not belong to the main mobile operators in Türkiye (Turkcell, Vodafone, Türk Telekom, etc.), but appears to be registered to a private company named “Nethas Bilgisayar Bilişim … A.Ş. (Nethas Teknoloji)”, based in Bodrum, Muğla.There is also a striking similarity between the trade name “Nethas” and “Netaş”, which is a well‑known and long‑established Turkish information and communication technologies company founded in 1967 to build the country’s telecommunications infrastructure. Because of this similarity in spelling and pronunciation, there is a serious risk that ordinary consumers or even some institutions may mistakenly associate “Nethas” with “Netaş” or believe that there is an official link between them, which could create an undeserved sense of trust.I would therefore like to raise the following concerns and requests.In modern smartphone‑based systems, mobile phone numbers are often tightly linked with device identifiers and various sensors (GPS, Bluetooth, Wi‑Fi, accelerometer, microphone, etc.), and this was clearly visible during the COVID‑19 period with contact‑tracing apps. In Türkiye, for example, the HES (Hayat Eve Sığar) code system used mobile applications and phone numbers to manage health and mobility data during the pandemic. Because such infrastructures technically allow location and movement patterns to be derived from smartphone sensors, there is an inherent privacy risk when private call‑center numbers and unknown third parties interact with users through the same phone numbers that are, or were, tied to state‑backed systems. For this reason, I respectfully request that the competent authorities also verify whether the number 0850 532 10 42 has ever been associated, directly or indirectly, with HES‑related or similar government‑integrated platforms, or used in any way to obtain or correlate personal health, location or identity data without proper authorization. I do not have direct proof of such misuse; this request is made purely as a precaution, based on the general data‑linkage risks documented in the scientific and legal literature on COVID‑19 mobile sensing and contact‑tracing apps.In Türkiye, Meta Platforms Inc. operates through its local representative (often referred to as “Meta Turkey”, including entities such as Madoka Turkey Bilişim). I do not have direct evidence of any formal relationship between this structure and the company behind the number 0850 532 10 42. However, if such a relationship or indirect cooperation exists, then the repeated calls made from this number could be part of a wider ecosystem in which phone calls, their costs, their timing and their stated purposes are influenced by, or correlated with, users’ online activity on Meta platforms – including what they search, view and write on Facebook, Instagram, WhatsApp or related services. For this reason, I respectfully request that it be clarified whether any data about my online behaviour (posts, messages, searches, viewing history) has been shared, directly or indirectly, with the entity using 0850 532 10 42, and whether these calls were in any way targeted or priced on the basis of such data.In addition, public complaint records on the internet show that this number calls a large number of people, often multiple times, without providing clear information about who is calling or for what exact purpose. Most people who receive these calls tend to perceive them as ordinary “internet / package sales” or marketing calls. Because of this, they do not see them as a security risk and do not question whether there may be a more complex or organized structure behind these calls. In other words, they think “someone just wants to sell me internet service,” and therefore they do not realize that they might actually be targets of something more serious.Online complaint platforms only display nicknames and short texts, so it is not possible for the public to know who exactly has been called, what their social background is, or what may have happened to them afterwards. Even if something serious did happen to one of these people (for example fraud, identity theft or other harm), it would be almost impossible for an ordinary citizen to connect it back to these calls. Because of this, I believe that the real purpose of the calls from 0850 532 10 42 may not be to sell internet service at all, but rather to scan and select potential victims and to collect background information about them. The “marketing call” appearance makes people lower their guard, which in my view creates a dangerous blind spot and may help to hide more serious activities behind a harmless façade.In light of the above, I kindly request that Meta:Clarify whether any of my Facebook / Instagram / WhatsApp data (including metadata, behavioural data and profile information) has ever been shared, directly or indirectly, with the company behind 0850 532 10 42, or with any third party that may be cooperating with it.Confirm whether any ads, recommendations, call‑to‑action campaigns or other targeting mechanisms on Meta platforms have been configured in a way that could lead to, or support, outbound phone calls from 0850 532 10 42 to me or to other users.Confirm whether Meta Turkey (or any local representative in Türkiye) has any contractual, technical or commercial relationship with the company operating 0850 532 10 42 (Nethas Bilgisayar Bilişim / Nethas Teknoloji), beyond ordinary advertising tools that any advertiser can use.Provide me with a clear explanation of what categories of my personal data are processed for advertising and targeting in Türkiye, and with which categories of third parties such data may be shared, especially in relation to call‑center activities and 0850‑series numbers.At this stage, I do not claim to have definitive proof of criminal activity by Meta or by the company behind 0850 532 10 42. My purpose is to formally record my concerns, to prevent possible abuse arising from data‑sharing or name confusion, and to request that Meta and its local representative in Türkiye conduct the necessary internal checks and, where appropriate, cooperate with national authorities to clarify these issues.Thank you for your attention to this matter.Sincerely,[Your full name][Country, city][E‑mail / phone]
