Vodacom is a ****. Don't get a contract with them

Definitely giving Vodacom a zero. I had to cellphone contracts with them that were supposed to end in August. They upgraded me to a new sim deal without my approval. When I inquired about it, they said they will reverse the upgrade, but I still paid for it. They kept promising to refund me as it was never my fault. Blamed it on a 3rd party call center agent. Then on my second contract I downgraded to the cheapest package(R59 airtime) so that I could keep my phone insured. That only worked for a few weeks and they did an upgrade without my approval. I discovered that from the monthly invoice. When I called them, they acted like there was never a R59 package, telling me it was discontinued. I still paid. I was promised another refund but nothing happened. End of October, I asked them to cancel my contracts and they kept ducking, telling me about 'your account is future open, we can't do anything. You will have to go back to the initial package, pay for it, and then we will cancel'. They promised another refund. Until now I have not heard from them.
