Disguisting service Cell c

I have had the worst possible experience with cell c. I don't have an account with them but 5600 was debited off my account. A ***** case was opened and to date 2 months later and still my money has not been credited. I'm basically begging these people to refund my money. How many other people has this happened to? Cellc is definitely not safe! Regards Khyola Pillay
