INTERNAL CONTRACT *****S & ZERO CUSTOMER CARE

MTN HAS THE WORST SERVICE EVER and i will never stop sharing my bad experience and telling anyone that will listen to never make the mistake of signing up with anything related to this company. ,My contract was due for an upgrade in JAN 2019 , when i called to completely terminate i discovered that an upgrade was done. This new phone was apparently taken from a mall on the other side of town, Carnival Mall. *** ? I had never set foot at this mall. Anyways i reported this as per their request, Affidavit and all. 3 Months later after i had begun reversing this EXTRA R1400 they later confirmed yes it was a ********** upgrade. Ok , fix your side so i can clear my accounts with you and Terminate as i had wished in Jan . Till this day , i have had more than 16 reference numbers going back and forth to stores, calling MTN with no help. Why am i paying for ***** done on my account that you acknowledged to have been a mistake ? MTN DOES NOT PROTECT THEIR CLIENTS , how do you allow someone to take an Iphone X with my particulars ? I thought you needed IDs, passwords, address and everything to verify this transaction. I am fed up because they're messing with my CREDIT SCORE now.
