Router network cut off

My Younger Sister wanted a router so ADSL subscribed her with a Telkom uncapped plan that is in her name and i am paying for the monthly premium is R669. On the 25th of october the first Debit Order was R768 which i did not understand as to y i was being debited more than what we agreed upon,i called telkom and to no answer held the call for about 26 min then afterwards i reversed the debit order in order to get attention. I then called ADSL and they put me through to telkom and they answered and told me it had administration fees which by now i still was suprised as to how were they not put on my contract or invoice i let it pass and i was adviced to pay via Eft which i did but after paying Eft i realised Telkom had debited again the amount of R768 the day before i called ADSL when i called to confirm if they received two payments they said yes and there is no way they can reverse one payment the amount will be carried over to the 25th of november.On the 25th of November i had no outstanding arrears with Telkom except for the debit order reversal charge which was an amount around R200 but on the 25th they deducted the amount of R669,i called telkom again and they told me i shouldnt worry in December i will just pay and amount of R113 on the 28th of December they deducted the amount of R113 well it meant me and Telkom were settled then around the 10th or 11th they debited again the amount of R113 to my surprise and i kept quiet and just took it that their saving me atleast that month i would pay less.Another suprise was when on the 15 of january i was debited the amount of R669 and my debit order date is on the 25th,from there i reversed the amount of R669 and R113 that was debited in my account called them and alerted them of the issue where i was told them that i m not going to pay debit order penalty fee as they had debited on the wrong day and we agreed and apologies for the inconvinience were said.On the 25th of January Telkom ddnt debit my account at all around the 28th i called telkom alerting them of this issue where month end an invoice was send showing that i will debited for two months on the 25th of february i dont dispute any of that This Morning the Router network was cut off after having agreed with the Agent that since well debiting on the wrong date and them failing to debit on the 25th and the 1st was not my fault i hope the line wont be cut off but to my suprise yet again Telkom cut of the line so now there is no internet connection still have to buy data and then pay double the amount for internet thats not working no ways.When i called i was told they cany re activate the line until the amount owed reflects my worry in experience to all that happend is that i might pay today via eft then on the 25th they debit me for the same amount.This is giving me grief and its not the first time because they failed to make me a sim swop of the number i had used to for close to 12 years after i was hi jacked and my phone was taken all along i called the call center with the same number and i was assisted i went as far as going to the head office and i was told there is nothing that can be done because the sim is not ricad in my name but they were able to suspend my line when i reported it ****** till today i cant access my cloud or reset all the passwords i got due to that number so Telkom just gives grief without solutions.
