Incorrect Billing | Known malfunction in billing system

You guys are starting to disappoint now. I keep on getting these threatening emails and SMSes from you.

I have told your call centre agents multiple times to escalate this internally. TFG had a malfunction on their billing system a few months ago, this was confirmed by your people when I first received an incorrect bill in May on the 19th. She told me telephonically what I am liable to pay for that month as instalment. Given the fact that this was a known issue at TFG, one would assume it would be fixed but NOOOO not with you guys. Now I'm harassed every other day by you. It's getting uncomfortable now as it has already started to affect my credit score (See attached).

I spoke to one agent who said the increase in instalment was due to an R2000 purchase I made in April. This can't justify an increase of more than 100% (from less than R600 to north of R1200 a month)

I am begging you! Get your act together.
