Vodacom

Goodday I have a very bad experience with vodacom. We had a data bundle contract with them. Last year March 2020 they phone is for a upgrade. They said it will cost less than the one we had. They said there will be no extra cost. The next day they took a double payment. I send it back phone them and cancel the contract. It is à year now and still I struggle to get the contract from our name. They still send me account's and phone me for payments. I don't know how to get it of my name. Up to date I just feel when will they stop steeling my money. They said phone calls are recorded but still no joy. If they could only listen too their recordings. We paid the amounts according to them just to get it of our name but still they want more money.
