Cancelled contract

This is my second time since September I'm sending a review about Vodacom. Since September Vodacom did not bother to be in contact with my husband regarding a contract which was supposed to to be cancelled in December 2020 instead they renewed this contract. I'm paying for a contract i cancelled. This contract is active and i don't have a sim card because i destroyed the sim card in December. I've been phoning since June to rectify this problem. Not one of Vodacom officers tried to contact us since June. I've send through a review on Hello peter in September they sen a reply stating someone will be in contact with us shortly it just never happened. We are struggling with Vodacom to refund us. It's almost a year and they still debiting our account
