DISGUSTING CO EVER

I've had a contract for many years. My acc is always around R500. Feb it was R2800 +...March R2500+. I am never on my phone. I am an 81 year old pensioner. There are *****ulent transactions happening on my phone. I NEVER requested any uncapping of any limits. Numerous upon numerous calls to the call centre, were no help. Given ref number, I phone back a few days later getting told THERE IS NO CASE. NO ONE IS LISTENING TO ME. I repeat the process again, getting a ref number..sent to various depts AGAIN. Many many many calls. 2 pages of A4 of notes. I get an affidavit, all info sent to ***** dept via the MTN store in Hillcrest. Again told NO CASE. MTN HAVE TO BE THE MOST USELESS MOBILE CO AROUND. I'M DISGUSTED IN THE WAY THIS HAS BEEN HANDLED!!!!! I WILL NOT STOP UNTIL THIS IS RESOLVED. THE MOST USELESS CALL CENTRE. I WILL KEEP ON TAKING THIS FURTHER UP THE CHAIN - YOU WILL NOT DE***** ME. BUNCH OF *******.
