Mtn

I am so disappointed in MTN I have been to there store in Worcester to ask them how it works to CANSEL my contract that is about to expire. They inform me that I must CANSEL on that day or after I did that,now that I call 135 they tell me I must give notice 1 month before and they added another bill to my name how can they bill me if the contract is Finnish 24 months old. I tried to CANSEL my contract from Monday but the system is always offline, slow or they will call me back that never happens. Hope to here from MTN head store my contact number is ***
