Turkcell Promised Nationwide Coverage but My Line Has No Signal

Based on Turkcell’s advertisements claiming to provide “coverage everywhere in Turkey,” I switched my mobile line to Turkcell before starting university. Unfortunately, my line does not just have weak signal—it has no signal at all. My family cannot reach me and is constantly worried about my safety. When I went to a Turkcell store and explained the situation, I was repeatedly told that I would have to pay an early termination fee. I honestly do not understand what termination fee I am expected to pay for a line that I cannot even use. I also filed a complaint with the Information and Communication Technologies Authority (BTK). Turkcell later contacted me and admitted that there is a lack of base stations in the area where I live, acknowledging that I am right; however, as a so-called apology, they only offered me 2 GB of mobile data to use in an area where the network does not even work. How ethical is it for a company whose service clearly does not meet its own advertising claims—and which misleads customers—to demand a termination fee when I want to switch to another provider that actually has coverage? There are two government-run student dormitories in my area with a total capacity of 1,300 people, and many other Turkcell users here are experiencing and voicing the same issue. Because of this situation, I will never consider using Turkcell again. The company has left me in a position where, if something were to happen to me, I would not even be able to contact anyone.
