Telkom charging clients for there fault

My debit date is 5th of every month on the on the 5th of january no debit order was done i phoned telkom numours times and on the 8th of january i was then advised i need to do an eft which i did that same evening they tried to deduct the money which ofcourse it bounced. On the 30th of January the amound payable was deducted again my debit order is the 5th, that payment went through on the 5th of february they tried to debit my account again! And now my next payment for the 5th of march is 200 extra because its a penalty fee as the amount on thr 8th of January bounced that evening after i sent the payment via eft that morning i was told by n consultant. I refuse to pay the ekstra 200 and telkom refuses to do anything about it becaus3 according to them it bounced and i should have paid 10days before! I paid as i was told my service was suspended. And another thinf they said on the 5th when it was supposed to go through it bounced on there side what a load of *******! I have proof on my side nothing went through thats why i was told i must do an EFT.Irefuse to pay for telkoms negligance! Sies on you
