Turkcell Bill Tripled After Commitment End – Excessive Charge Complaint

I am a Turkcell Dolu Eko 20 GB line subscriber. After the commitment period on my line ended, my bill was almost tripled without any reasonable or clear explanation. While I paid around ₺307 for the June 2026 period, a very high amount of ₺907.50 was reflected on my bill for the July 2026 period. I know that an SMS may have been sent regarding the end of my commitment, but I did not receive any phone call or verbal information. I believe that such a drastic increase, especially an almost threefold rise compared to the previous month, should be clearly explained to the customer in an understandable way and their explicit approval should be obtained. After this incident, I tried to reach Turkcell customer service, but it is almost impossible to connect with a real representative on the phone. I am constantly directed to the robot assistant named Teknocan, which keeps repeating the same sentences like a parrot and does not offer any concrete solution or clarification about my bill. I request that this sudden and excessive increase in my bill be examined, that the unfair difference be canceled or adjusted to a reasonable level as compensation, and that I be clearly and transparently informed about the new pricing that will apply to my line. If necessary, I can provide the invoice screenshots showing both the June bill of approximately 307 TL and the July bill of ₺907.50, as well as the current package details for my Dolu Eko 20 GB line. My line number is 0535 77* 86 ** and my name is Abdurrahman A***.
