Telkom messing me up!!!!?

Hi, I need to lodge a complaint regarding the 2 debit order Rejection charges Telkom have included on my account because of their own staff incompetence which now is inconveniences me as I have a full time job to deal with rather than running around and fixing Telkom problems. 1. I called their call center in February 2018 advising them of banking details change and the person who updated my banking details advised me that it won’t be going off in February and only will start in March and I was advised to pay my account cash which I did not have a problem with. I also called back a few days later and confirmed what the agent told me that the debit order won’t be going off my bank account and I made payment via EFT on the 23rd February 2018 only for the debit order to go off after I already paid!! I called my bank and reversed the debit order (WHICH BY THE WAY MY BANK CHARGES ME FOR DOING A DEBIT ORDER REVERSAL!) 2. At the beginning of the Month of March , I went to The Pavillion and advised a lady by the name of Gwen to advise that I won’t be upgrading my contract for ********** 792 that was due for an upgrade and needed it terminated and in a process requested the Debit order to be cancelled as I had decided that I will be making payment by EFT since I was still ****ED OFF about what had happened in February but since your company is always getting it wrong the detit order was not cancelled and again same thing happened I pay via EFT and you go debit me and AGAIN I end up having to tell the bank to reverse the debit order again ! I have gone online yesterday and have notices 2 charges of R200.94 for Payment rejection fee in my account due end of April 2018 !!!! Are these people crazy ?????????????? How does the Telkom staff incompetence end up being my problem and have to be charged and pay for it? It’s enough that I have to deal with Telkom’s poor network coverage everyday BUT this I cannot deal with!
