I'm not happy about their service

I'm not happy about their service. I paid for a contract for 24 months for the services which I didn't receive from them. My contract number is ***. When I wanted to upgrade, they gave me the wrong product, which was home internet, instead of the previous package that I have been having with them. I made efforts from the beginning of the upgrade, to understand why I couldn't get access to internet, but I couldn't be assisted. I was advised to buy a new sim card, which couldn't work too, until the contract ended and my account was still debited for services which I couldn't get for the entire contract period. What I want from VODACOM is the money that they have debited from my account, with bank charges and interest. Plus my money for the new sim card. The contract period in question is from January 2023 to January 2025. I will appreciate your assistance.
