The worst experience ever

I tried canceling my vodacom contract but instead I was upgraded. I don't even have the Sim anymore which l explained to the consultant but he upgraded instead of canceling the contract, he even added a 50g data to the value of R694.78 that I didn't ask for on a Sim I nolonger have. I've been calling vodacom to fix this mess and they still haven't. Stay away from vodacom guys, they are ******. They don't care about you, they just want your money.
