Cell C contact not being cancelled.

I was a loyal Cell C customer for many years and had to cancel two of my contracts because there was little to no signal in the area I lived. this was in 2017. Just to find out on Tuesday (09-02-2021) that one of them had been cancelled. So, I went to the nearest Cell C shop in Bloemfontein to find out what had happened and why was it not cancelled and why I never got informed, but instead of getting answers I was left with more questions as the very helpful staff member at the Preller Square store showed to me that both account had not been cancelled. He advised me to phone Cell C customer care, which I did and could not be helped either as the helpful lady on the call center gave me the contact details of a person that handles the accounts that have been handed over, which could not assist me either as these are contracts that have been cancelled instore at the Cell C Loch Logan branch how many years ago and was told that they will be cancelled. The SIM cards destroyed instore as I do with all mobile contracts that expire has shown no activity at all according to the lady from the Cell C customer care call center. The account has been handed over without my knowledge and after all there years I am expected to pay for a service that I cancelled and services I never used since. And going back to the branch I cancelled the contracts will not help either as it has been permanently closed. Now I ask the question, how and what now Cell C ?
