Extremely poor service

I have logged a dispute with XDS nearly a month ago as their credit report reflects a poor rating due to debt review, which I have never been on ever. The debt review only appeared recently and it dates back to 2009. Since 2009 I have bought a number of vehicles with out any problems, now all of a sudden because of XDS I am having issues getting a lone. All the other credit report companies have my credit rating at excellent. I have also tried calling there call centre and have not got through even once after endless trys (Currently been on hold for 9 mins). How can a company that reports on issues that affect your lively hood be so unprofessional?????. Are they maybe getting kick backs from companies that help with clearing you credit report..... it makes you think.
