Cancellation nightmare. R417 overcharged, 192 minutes wasted.

I've been overcharged by R417 by MTN.

I cancelled a contract, paid the early cancellation fee way before my next order date and confirmed the cancellation numerous times telephonically. But I have still been billed after the contract was cancelled, and an extra amount of R167 has also been billed.

For 10 days I've been trying to get the problem solved. I have made 12 phone calls, and I have spent 192 minutes. Today I finally went into the store, since it has still not been resolved.

MTN cannot explain why I'm being overcharged, they can also not prevent the debit order from being changed. I can only log a dispute and hope that it will be resolved. They cannot offer any solutions or any confirmation that my money will be returned.

I will be cancelling all my contracts as I cannot afford for people who are not competent to manage accounts to overcharge me and manage my account, and not be able to help me solve the problem.
