Turkcell Switched My Superbox Plan Without Notice and Raised My Bill

Even though the commitment period for my Turkcell Superbox 200 GB subscription, linked to the phone number 535 360 8945, ended in November, I did not receive any notification, message, or warning informing me that my contract was about to expire. Because of this, I was not aware that my commitment had ended, and without my knowledge or consent, my line was automatically switched to a non-contract plan with much higher fees.

I paid my December bill, but when I saw that my January bill was much higher than in previous months, I contacted customer service. During the call, I was informed that my commitment period had ended and that this was the reason I had been moved to a higher-priced plan.

Despite this, no discount, refund, or solution was offered. In addition, when I asked to open a formal complaint record, I was repeatedly told that a complaint could not be created.

I am aware that sending a notification at the end of a commitment period may not be a legal obligation, but I strongly believe it is necessary from a customer satisfaction perspective. Since I was not informed that my commitment had ended, I do not accept the high charges that resulted from this situation. I request that the charges applied under the non-contract plan—especially my January bill—be reviewed and corrected, and that my grievance be properly resolved.
