Unfair Blacklisting

The past 3 weeks i went to the Edgars store to ask that my account should be updated at the ITC because i tried applying for a loan and it was declined due to the ignorance of the Edcon people not updating my records on ITC yet they quickly updated it when i skipped a payment. i paid all the money i owed 2 to 3 years ago and my record is still not updated. I reported this matter on this site and today i requested my credit report again and it still tells me my record hasn't been updated. i got an email with phone numbers from Phumla Mhlanga telling me that the request has been made and gave me a number to call. i call that call center number and when i choose options it hangs up. i need to apply for a loan again Wednesday and its still going to be declined due to this problem that Edcon has got me into. If this matter is not solved by Wednesday the 9th march 2016 and i miss a chance of getting that money im taking you guys to court.
