Deceived and **** to me

On the 29th of September I spoke to a representative of Mondo as my contract was extended by MTN against my wishes and without informing me that it will be a early upgrade. The representative of Mondo got back to me to inform me that MTN was in the wrong and will reverse the upgrade because the representative did not inform me of the early upgrade fee (note that they only told me because I called and they did not contact me). They were then going to cancel the contract, after a week I called and the said the cancellation will take up to 14 days. I called today just to be informed that my upgrade was not reversed and they now can't assist me with the cancellation. They will not provide me with the recordings unless I go into a MTN store??? Called MTN and they were also of no help as they no first need to get a reference number from Mondo and then they can look at it. I informed them of the urgency as I am leaving the country on the 3rd of Nov 2022.
