Telkom Accounts and Call Centre Useless

Issue: About a month ago I ran out of my 10 Gig ADSL data bundle so I called the call centre and asked for another 10 Gigs to be loaded once-off. A few weeks later I received an incorrect bill, I called the call centre and was told that the incorrect billing product code was used. While the additional 10 Gigs was supposed to be about R 100.00 I had to pay an additional R 500.00 (approx). and added to that, the additional 10 Gig service was on my account to be repeated every month! I guess I am being billed for 2 ADSL lines with 10 Gig data bundle each!? During my last call to Telkom accounts I was told that they will send this through to the accounts or crediting department to be corrected. Today, about a week later, I receive an sms warning that Telkom will terminate my line if I do not pay my bill immediately! Credits has to be passed, product codes corrected on my account etc. What the heck is going on? Actually, I should not be surprised, just sad. <br> Is there someone who is able to resolve this properly?
