Emotionally drained customer by Vodacom

Vodacom has given me the worst service since last year December. I went with my brother to open a contract with the special they were running during December, they kept telling us to return the next following week until January then told us the special was discontinued. Regardless of the fact that we took the phones during the period of the special, buy because I didn't have a phone I just decided not to fight that and take another contract.

With my new contract they linked my brother's details to a number that's owing alot of money, on top of that I paid my contract and received no data. Everytime we call the call center we dnt seem to get any help and the store itself is of no help. Now my brother inherited a debt due to their negligence, they caused us alot now I just want to cancel the contract and I don't want to be told to pay alot of money simply because they could not deliver good service to us
