Bad service

Bad service from MTN. I missed a debit order on the 25th of September 2023 and I made payment on the 2nd of October 2023 on my month to month contract but I still don't have internet. I spoke to the agent on the 3rd of October and the agent told me that I am not going to get data because I paid after the date of allocation of data. I spoke to MTN on and this is what they said "Kindly note that on month to month contract, you get provisioned when you make payment, not on your bill cycle.

M.M" I just spoke to an agent now who hung on me while I was still talking. I need assistance as it doesn't make sense that I've paid my account for free. I need to get reimbursed then.
