Bad cancellation service by MTN

MTN is quick to write new contracts or to help you with new data, but when you want to cancel your subscription, they make the process so lengthy you wish to give up. And that is the plan they have in place, so you don't exceed in canceling your contract. I went to Vodacom about three years ago, and still, up to today, they are debiting money from my account of extra data. Going into the shop to try and cancel it, they are not allowed. They need to phone in, and that took about 15min with no response, and as I said, I gave up and needed to go. But ask to write a new contract, MTN will line up to help you in 5min.
