Worst service ever

I'm so upset with vodacom, I canceled my contract September 2020 filled out the premature cancelation form paid the amout to cancel the contract and today we are in month 4 of 2021 8 months later they still have not canceled my contract I have been in store to give my documents i have sent it to multiple people i have spent hours calling them. And they stil could not help me. Meanwhile we have been rejected for a home loan because of a R 199 contract. This is unacceptable.
