MTN - HORROR OF A SERVICE PROVIDER - AFTER BEING WITH THEM FOR SINCE +- 1997

I have been with MTN with this very number *** for almost it not already 30 years. In my life I HAVE NEVER exceeded a bill of R2k I DID NOT PURCHASE whatever this means I DID NOT SUBSCRIBE TO GAMES TRAIN OR HUSTLER I DID GO INTO YOUR NI CITY STORE TO DO AN UPGRADE I DID ASK THE CONSULTANT TO CANCEL ALL SUBSCRIPTIONS TO WHICH SHE CONFIRMED THERE WAS NONE HOW COULD YOU ALLOW ME APPARENTLY TO GO OVER MY ALLOWED FREE AMOUNT, AS ALL MY CONTRACTS WITH YOU IS CAPPED I HAVE WIFI AT HOME AND AT WORK, I DID HAVE NOT NEED TO PURCHASE DATA, AND ID I APPARENTLY STREAMED (AS THIS WAS THE REPONSE I GOT TO THE EXCESSIVE BILL) I WOULD USE MY WIFI AND NOT DATA THIS VERY NUMBER I HAD A STUPID CONTRACT, BEFORE THIS LAST UPDATE, AN AMOUNT OF R59+ JUST TO GET DATA AND TO KEEP THE CELL NUMBER. MTN debited my account with R20K. I then had it reversed and paid my normal bill which came to R1.4k. As of last night, I could not use my cell phone as it was blocked. Why block all my numbers if they have an issue with only one of my cell numbers.
