Nightmare Cancellation

I would give your customer experience a zero, but option doesn't exist. I took up a contract with MTN and paid it as promised never missing any payments, and at the end of the contract i sent an email to them to cancel, then made a call to the call center for a cancellation which was confirmed. After that my nightmare started, from being handed around from one department to another, to being cc'd on the email where the staff was asked to action the cancellation, which was not done, to being handed over to attorneys for collection. This has to be the worst network by far. I am a specialist in customer experience with many years of experience and they have the worst i have seen.
