Incorrect Debit

Last week I had a telephonic conversation with Patricia in the collections department, who couldnt really explain why the debit on my account had stopped. The previous debit order had been reinstated, amounting to R603. This morning, my account has been debited thrice, as follows: Vodacom *** - I*** R9839.72 R232.04 R603 Can someone please explain why a debit of R10 674.74 was raised on my account? My patience is wearing very thin with the customer service. This is dragging my contract longer and longer. Will vodacom pay the account fees on my NOW overdrawn account? I called Patricia on ***, which she advised, is her direct number, the line just rings, I tried ***, to which my contract number *** is an invalid number according to the system, so I cant get through to an agent to assist.
