Telkom the absolute worst service ever

I am very upset with Telkom. To start off my contract was meant to be R170 topup. all inclusive. I am a single working parent so I could afford this. From my first payment the amount deducted was R213.30. [That was after a double payment and the R99 delivery fee ect] In October I defaulted on my payment, which goes off on the inconvenient date of the 15th of the month. They deducted the amount of R213.30 on the 28 Oct. Ok so I thought it was now paid. But then on the 15 Nov instead of deducting my payment they deducted R208.00 - which a consultant explained is their default fee. But they did not deduct my payment, and there was sufficient funds. But then on the 20 Nov they tried again to deduct the R208.00 [default fee]. I obviously did not have the funds and it defaulted. Then on the 25 Nov they deducted again R208.00 [default fee]. .....Still not deducted November's payment! So if I under stand this correctly they deducted 2 default fees in November and tried a third time....which defaulted. Still have not deducted my payment. On going to my bank, which I have a really good credit record, I was dismayed to discover that my credit record has been severely affected because of Telkom, and my next payment at Tekom is standing at R635.00 When doing my own credit check Telkom shows my contract as R635 and not as R170.....or R213 as they charge me.
