NOT HAPPY.Telkom MESSING up my NAME at the credit bureau.

I've had a contract with Telkom for May years, recently I changed it. My contracts have been month to month. Since then I have been debited every 2nd month due to a fault on telkoms side and it then reflects like my account is in arrears. I have no control over when Telkom debits my account. You then handed me over to debt collectors so my credit score has been decreasing since I changed my contract and IT IS NOT MY FAULT BUT TELKOMS. Please arrange for whatever negative impact this has on my name be removed by the credit bureau. I would like for somebody to contact me and rectify the problem you have created.
