telkom biiling issues

my name is solomon katlholo motiang, i have been using Telkom for about 3 to 4 years now, my problems starting last year September when the service provider failed to debit my account on the agreed date, as i understand its my responsibility as a user to make sure that the are funds in my account on the date of the debit as agreed with the service provide, then in the case where the service provide fails to debt my account on the arranged and agreed date, so now my account is in a huge arrears dur to failure of the service provider, i tired a number of times to get this issues sorted out by means of sending in my bank statements to show that their was funds in my account on the arranged and agreed date of debt order and went to an extend of making direct payment to sort the issue out but instate this continued until now where they provided assurance that my account is in order and the debt date its corrected come the date no money through and later on they request me to make direct payment.

I believe that Telkom as the service provider have a duty to perform certain tasks as per contractual agreement and its failure to do so its a bridge of contract and i as a user i must not be penalized because of that, as i a client if i fail to make payment they disconnect my account and my services as suspended,

i hereby making a urgent quire to check this issue and come up with the best probable solution to this matter.
