MOBROG Spam Call Possessed Full Name and Phone Number Without Prior Authorization

I was called twice from the MOBROG line at 0 (312) 963 49 74, and the caller claimed to represent a holiday resort while requesting to conduct a survey. During the conversation, they already knew my full name and specifically referenced the Hatay-Erzin region. Despite never sharing my details with this phone number and having no recent record of registering my personal information with any holiday company, tourism agency, or similar establishment, the fact that they possessed my full name and phone number has deeply disturbed me.

I demand a clear explanation as to which source and through what channels my personal data was obtained by this number. I am extremely uncomfortable with my personal information being shared without my knowledge or consent and being contacted in this manner. I request that this matter be formally investigated and that a clear, direct disclosure be provided to me.
