You admitted your fault, then gave me bad credit?

I went through a whole customer service situation whereby Telkom had made a mistake and had incorrectly billed me for over a year for a product I didn't receive. <br> <br> You admitted your fault, but then STILL registered me with bad credit and a bad payer. I expect you to resolve this and write a letter to confirm this was NOT my fault. <br> <br> Ridiculous. I am being punished for Telkom's internal errors. <br> <br> Outside of that I think your product and service is fantastic. Just want you to be accountable for your mistake and fix it.
