MTN contract cancellation- endless nightmare

They do not deserve a rating, I opened a contract ithe beginning of July, cancelled within the notice period.To this day I am still being debited monthly, cannot get hold of them, the emails they do reply on say they have cancelled the contract but I'm still being debited 5 months later! None of the numbers work and when you eventually get through, you are transferred to a number a drops your call. DO NOT OPEN A CONTRACT WITH MTN, YOU WILL REGRET IT, ENDLESS HASSLE.
