Vodacom

I have a BIG problem with Vodacom in December they debited money from my account with out my permission to make things worse i dont even use a Vodacom sim card. Since January i have been calling them, asking them to credit my money back but no money has been credited back into my bank account all they do is credit the money into a Vodacom account that they say is mine BUT mind you i dont even have a account with Vodacom. I have reference numbers to prove that i have been calling more than once. I once spoke to a guy by the name of "Masala" in the Subscribe Department and he promised me that i will have my money by the 19 February but still here i am on the 27 February i still haven't received my money back. I am not one to complain but i dont think it is fair that i have to be asking for my money for two months it is my money after all. The accounts department in Vodacom is USELESS!!!!!!
