Incorrect Bill from Telkom and terrible service

I joined Telkom in September, on my inception date I was still a Standard bank client, on the same month I called and requested my banking details to be changed since I was moving back to FNB, I was constantly told they were offline I should go to the stores, when I got to the Telkom stores I was told to call the call centre, I did not win either way, so I paid my account manually. I am suspended due to none payment, I really don't know how because I made it a point a pay, December a miracle happened, the call centre staff actually captured my bank details ,but I have not been debited, my bill is incorrect, as far as I know I owe R597 for my mobile and R1107 for the router, can someone please help because I am really getting frustrated with this company.
