Vodacom contracts

I paid my account and I was debited AGAIN. I want to know why and I want the money taken from my account back into my account. This is unacceptable. I don’t know why I have to constantly write bad reviews for Vodacom because of the bad service. If this is how it’s going to go then I will close the account and go somewhere else. You people are quick to take peoples money but don’t even answer your phones when customers call. Absolutely disgusting
