WORST SERVICE PROVIDER. DO NOT TKAE OUT CONTRACTS WITH THEM

I HAVE BEEN A LOYAL CLIENT OF MTN FOR OVER 10 YEARS. I HAVE NEVER MISSED A PAYMENT OR EVEN SHORT PAID. THEY KEEP DISCONNECTING MY PHONE SAYING I OWE R597 DUE TO A SHORT PAYMENT DONE IN JULY 2020. THE MORE I SAY I HAVE NEVER SHORT PAID. THEY HAVE ADVISED THAT THIS HAS NOW BEEN SORTED BUT GUESS WHAT? MY PHONE IS DISCONNECTED AGAIN. I HAVE SENT MY BANK STATEMENTS TO PROVE I HAVE PAID IN FULL IN JULY BUT THIS IS NOT HELPING I CANNOT WAIT FOR MY CONTRACT TO END SO I CAN RATHER MOVE OVER TO VODACOM BECAUSE I HAVE HAD IT WITH MTN AND THEIR ISSUES AND LIES.
