I use a postpaid line, and the charge is shown as related to the number 097150923******. This fee appears on my October 2025 bill. When I contacted Turkcell customer s...
I switched to a Turkcell postpaid plan after being assured repeatedly—both at branches and through the app—that I could cancel within one month without incurring any fees. Trusting this, I decided to move back to Türk Telekom just three days later. However, I received a bill on January 10, 2025, sta...
