Vodacom are *****ing my money.

I wish i could give a minus 5 rating!!! After 24 months I want to cancel a contract at Vodacom. Contract end 30 Sept 2020. I phoned Aug to cancelled it. From there I phoned every month up to now in Jan 2021 tried to cancel this contract and they still keep on debit my account. It seems the cancellation department are not competent to do that and nobody can help me. I'm 21 years with Vodacom but never again.
