Disappointed client

I have 2 contracts with vodacom. Which suppose to end in October 2023 however my contracts have been extended till April and June 2024 due to a consultant applying a covid relief which I did not agree to. I've called the customer care and retention department numerous time and there was no help. I've even visited a vodacom store still no help. This is frustrating as I'm not going to pay for another 6 to 8 months for something I didnt agree to. This is unacceptable.
