Cannot pay accounts and told to change to a different bank.

This is the second year , i have experienced this issue. Every time Capitec changes my credit card, although international payments are enabled, I cannot pay my MS Office subscription. I called the Capitec support desk, and had a range of answers. The one person told me i need an account at a different bank to pay Microsoft. Really? I am encouraged not to pay my Office subscription at Microsoft or change banks in order to be a legal user? And a blanket over all MICROSOFT payments- none can be done? If this is the case. I will close all my accounts with Capitec and move my accounts. After 3 calls to the call center, can somebody that can actually assist please contact me?
