Non-existent account showing on ITC

I had a Telkom account but it was cancelled in 2013. In applying for a bond in 2016, the bank ran a credit check and the Experian report states that I pay Telkom a monthly instalment of R 287. 00. This is obviously inaccurate. I need someone from Telkom to contact Experian and verify that they can remove this false information. And I need confirmation in writing that I do not have a Telkom Account. This issue is negatively affecting my affordability for getting a bond and I'm holding Telkom responsible for this. I sent an email via the Telkom website last week and not a word of response....
