Vodacom - Good at blaming the customer, poor at taking responsibily.

I downgraded my line a month ago and suddenly have services appearing on my bill that I did not sign up for. When I phoned the support centre I was told "we cannot help what our customers do on the internet". Simply put, I have never signed up to any services using my mobile number. A lifetime of online behaviour is not going to conveniently change since downgrading my line. There has been an error and it needs to be addressed and not brushed off as a user problem. I have also since read many forum and thread posts of other customers having this exact issue. I was also told by a support agent, called Jeffrey, that his team lead, "Cheza Ramafare" (who I am not convinced is a real person) will call me. I never received the call. Poor service and actions that are in direct conflict with the Consumer Act seem to be standard for Vodacom.
