MTN - Worst Customer Service In the World!!!!!

MTN is ripping me off - from activating me onto the incorrect tarriff - to waiting a week for my sim to be delivered, to waiting a week for my number to be ported over , then finding out that i am on the incorrect tariff, to having to buy over 400rands airtime to resolve the query . Sloppy advisor's , sloppy customer service . Oh and the worst happened today , so i finally get activated onto the correct tariff yesterday and then today i got to a 4 hour training session as i am also in customer care- only to finish training and find out that my line has been suspended- call into the call centre and get advised that i have attempted to buy something that cost 800rnd. *****!!!! i didnt even use my phone, i deciede to call from my agents phone only to be told that i cannot cancel as i will get early termination fee's, i disagree with the agent , who advises me that he will put me through to the LEGAL TEAM then they cold transfer me and i have to explain my hole situation again to this agent who again could do nothing for me and cold transfers me back to retentions. I am fed up and if nobody calls me within the next 24 hours , i am taking this to court!!!!!!!! you are in breach of your terms and conditions of your contract that clearly states that i can cancel if you are in breach and yet you still wanna charge me Early termination fee's.
