Deceived and **** to me

MTN extended my contract after I informed then I need to go on a month to month contract as I am in the process off emigrating. After contacting Mondo on 29/09/2022 they investigated and found that I was not informed of the early upgrade and it will be reversed. I followed up during the month during the month of October and was told by the Mondo representative that they are busy with the cancellation but will take 7 to 14 days. I called to day to find out the new contract was not reversed and they did not cancel the contract.
