On April 12, 2024, while serving in the military, I visited the Turkcell branch in Karşıyaka, İzmir, to switch from a restricted line to a regular one. However, I was told that I could not switch to a prepaid line and that I could only switch to a postpaid plan, which I reluctantly accepted. Later, I learned from your customer service that there was no such requirement. When I requested to terminate my line without a contract, I was told I would be contacted, but months have passed, and no one has reached out. Now, when I want to cancel my plan, an early termination fee is being applied. I provided Turkcell customer service with the branch name, address, contact information, and the name of the employee responsible for this issue, but no solution has been offered for months. I will escalate my complaint to the Consumer Arbitration Board and CIMER, filing a formal complaint against both the Turkcell branch and the employee. I am certain many other military personnel have faced similar treatment at that branch.

Only six days later, on September 26, 2025, I canceled my line at the same store. However, even though my bill had not yet been issued, I was informed that an early termination...

Turkcell was notified of my intention to complain with the Consumer Arbitration Committee and, if required, to pursue legal action. I felt let down...
On May 25, 2024, my Turkcell postpaid plan was renewed. My 20 GB plan was exhausted in just 6 days. Turkcell claims it's due to my usage, but I've been using the same plan for months, and it's impossible for me to finish it in 6 days. That's the first issue. The second issue is when I tried to canc...
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...
I submitted a request to switch my Turkcell line to prepaid, but they didn’t process it. I called customer service a second time to cancel the request immediately, and they told me another department would call me. I asked to be transferred directly, but they didn’t connect me. I told them to create...
