No Response, Bad Credit

Hi. We had an account with Telkom, number ***. It was a voice line and a ADSL line. 1st of December 2013 we moved house. We cancelled the lines as there were no ADSL lines supported in the area that we moved to. Then we got another account. Then it took my wife 3 months to sort it out, explaining that she have stopped the account. 04 March 2014 we got the final account for R353.97. On 15 June 2014 we decided to just pay it after Revco sent sms we need to pay. Then earlier this year we got a shock when we app**** for a home loan that Telkom has put us on the ITC for bad credit, although it was their fault. Now it is more than a month that we try to get our name of the ITC. We have sent numerous requests on the Telkom website, and get response that the account is paid up. My wife called the Telkom call centre a few times, but she is getting nowhere with them as well. Still our name stay on the ITC. All we need from Telkom is just a simple e-mail that say we do not owe them a cent. I am going to see a lawyer next.
