Disappointing service

I have six contracts with MTN and had them moved to a business account last year and two of the contracts was not moved. We tried again this month to move the two and first i was told that they can’t move it to the same business account and a new one had to be created for the two contracts. I asked them not to do that and cancel the move. a few days later they moved the two contracts to the other four contracts. I went into a MTN store today to upgrade my two accounts and now it can’t be done. the upgrade date was originally the 06/07/2024 and then it changed to the 13/07/2024. Now I must pay in even though I have had my two phones for 36 months.
