Telkom *****ing my money!!!!!!!!!!!!!!!!!!!!!!!!!!

For over 2 months now Telkom have been deducing from my account throughout the month i have no funds in my account at that time amd then i have to pay bank fees for debit order that was unsuccessful they did not stick to the date we agreed on to deduct on the 28th they just deduct when they want to. I called again this morning they informed me that my account is at collections "i did not even know i owe them any money" they never called the lady told me they can deduct anytime throughout the month i was furious and told her you cant deduct at any time how am i supposed to know when you are going to deduct??? I will never ever use telkom again!!!!!!!!!!! I asked the lady to put me through to collections ahe said customers cant talk to collection TELKOM SUCK!!!!!! PLEASE DONT USE TELKOM USE ANOTHER NETWORK PLEASE!!!!!!!!!
