Poor customer service

My contract installment was not debited in June because funds were only available on the 1st July I called telkom to ask that they debit and they told me to pay manually or alternatively they will debit with the next installment end of July and she informed me that they do not use the nae-do tracking facility. my debit order date is the last day of the month on the 25th July telkom debited my acc with R520 of which I reversed and on the 31st there was money in the acc however they did not debit I called in on the 1st August spoke to Thandeka Mbatha who was very arrogant and rude and she said they blocked my router due to arrears I asked that they debit the installment and she said I must ensure that payment is made i am now without internet due to ignorance from telkom of which its not even my fault
