PAY FOR SERVICE NOT RECEIVED

I signed up for an internet package that was supposed to give me 50G of internet access at 7000 rand per month. I got the service for exactly two weeks and that was it. I have been to Telkom office cresta several times and my problem has not been solved. I have been unable to get them to sort out my problem. This afternoon I get a phone call from Telkom saying \DEREK NDINTEH this serves to inform you that your Telkom Service account number *** have been suspended and will subsequently be dismantled due to non-payment. Please note that should the full amount of R 4127.45 not paid immediately your account will be handed over to our attorneys for collection and your details listed with the credit bureau. Thank you for your cooperation on this matter..
