Turkcell Failed to Replace Lost SIM Card Leaving Postpaid Line Unusable

I am a Turkcell postpaid customer, and I lost the SIM card belonging to my line, so I have not been able to use my line since 29 November. Since that date, I have repeatedly visited the same Turkcell dealer in Ankara Kızılay and requested a new SIM card. Each time, I was told that the SIM card would arrive in “2 days,” and I had to go to the dealer about six times. During my last visit, when I asked how a dealer could have no SIM cards, I was told that they only receive 10 SIM cards per week and that it was unclear when new ones would arrive. After this, I contacted the Turkcell communication center and explained the situation in detail. However, they also could not offer a concrete solution and only suggested that I visit different dealers. I went to three different Turkcell dealers in Ankara, but none of them had SIM cards available, and I still cannot use my line actively. Although I pay around 400–500 TL per month for my postpaid line, I have been unable to use my line during this period and have not received any solution either from the dealer or from the communication center. I request that my grievance be resolved urgently, that my new SIM card be provided as soon as possible, and that the fact I have been unable to use my line during this period be taken into account, including any necessary adjustments in my favor.
