Telkom billing for closed account

<p>I don't understand how Telkom can continue billing for an account I followed procedure with in closing... however after communicating with someone who I thought was very helpful in resolving my issue turns out... we were not on the same page... guess what happened next... I've been listed as having "bad debt written off" on my credit record for money that I don't understand how I owe... and that is the thing... from being told that I was being billed in error and the amounts charged will be reversed to "bad debt written off", how did this happen? I'm really disappointed and any communication with them has fallen on deaf ears... </p>
