NO HELP - NO SERVICE - BAD,BAD BAD!!!

My line got cut. 3 x cell contracts and 2 x data contracts that I have with MTN. Turned out - R9500 data used. I was informed my limit is R8100. Who allowed it to be so high and why R9549. If I have R100 how can I withdraw R150. My limit is R8100..that I was not informed of either!! I paid it all the next day and sent proof. Upgraded to 5GB capped rooter. Received only 2GB the next month?? 7 days later MTN deducted R9500 from my account .As I've already paid it I reversed the payment at my bank. My account got blocked again cause MTN did not link the payment with my account!!! Its nearly 2 months now!!! My other cell phone number got mixed with a Foschini account. For 2 months I pay it but cannot use it. On my number my data and sms's are not linked. I pay for it but don't get it and then gets charged MTN tariffs when I use data/sms. I pay Unbilled items cost for more than a year now on top of my normal contract fees!! Received sms on weekend that MTN will deduct R9652.75 today..REALLY?? JOKING? Phone them every day- no answer..just a simple tone that play. Nearly 2 MONTHS NOW-NO SERVICE!! Visited branch more than 10 times. No reply to branch mails by head office. REALLY FRUSTATE
