Never ever take out cellphone contracts with Vodacom- horror stories!

My contract eith them ended mknths ago. They keep deviting my account ahve put me in arrears. From what I've seen, it's going to lead to blacklisting. I have been to different stores and they keep turning me back with no assistance. I email and try to call with no success. Every month, these people ***** my money for a contract that has expired and tell me I need to call to cancel. I see many of us have the same problem with them. Why is the law not protecting us against this network? What does the Consumer Protection Act say about this coz there's no way so many of us can go through this and still let them get away with *****ing.
