False report sent to a service provider

I surely know about the legislation: Consumer Protection Act and the Credit Act against false reports. I had a red face after the manager of MTN Jeffreys Bay smilingly told me I was a bad payer as if I am the greatest lier ever. We phoned ITC Trans union twice to get an e-mailed report which they sent after two requests. The report was completely clean of any negative reports. No judgements, no nothing. MTN submitted my application to their HO who declined my application : Bad Payment Profile, contact ITC - Application declined in revet prospect. It was a humiliation!!! I am a manager of a big organization with a good salary and never had any problems paying my bills. I am goint to see my lawyer about this, and I want ITC Transunion to give a extended explanation about this. I am not going to leave this as I was humiliated in front of other people who looked if they feel sorry for me. I surely also will contact the Credit Regulator and lay charges against Trans Union ITC. They also are one of my clients as I am a Credit Manager, I will cancel my contracts with them. There are other service providers . ITCTU couldn't give any info bout bad payment history cause there is no such hist
