Turkcell Reactivated a Package I Had Already Canceled

I was charged ₺5600 for my Turkcell postpaid line for the month of June, and upon inquiry, I was told this unusually high bill was due to the activation of the TYG Avantaj package. However, I had already requested the cancellation of this package during a previous activation, and the cancellation was confirmed. Since May, I have been abroad and have not used this package at all. There were no similar charges in the previous months, yet Turkcell issued an inflated bill solely for June. I had no knowledge of the package being reactivated and did not authorize or use it in any way. I am requesting the cancellation of the ₺4500 charge specifically related to the TYG Avantaj package, which I never used. It is unacceptable to be billed such a large amount for a service that was neither requested nor utilized. For your reference, I have attached screenshots showing my previous billing amounts and the incorrect charge applied in June, and I kindly ask that this issue be investigated and the unjustified amount refunded as soon as possible.
