Black listed due to ********** Suppliers

I app**** for a home improvement loan at Real People and my application was referred to Modeza Trading t/a M-Hardware to supply me with the material.I qualified for R30 000.00 and only used up R13 290.00 worth of material as I only needed the money for a Painting Project. I paid up the R13 290.00 as per invoice to the suppliers.Early this year I app**** for House loan only to find out that I was Black Listed for the R30 000.00 plus interest, to the balance of ?R41 912.15. I complained a few times and have faxed through numerous complaints to their Complaints Department to resolve this query but was literally sent from pillar to post, I eventually spoke to Lee Anne on the 29 of January who advise me to look for the proof of payment before they can start with the investigation. Unfortunately I cannot find the proof of payment.<br> My problem is when querying with Real People about their suppliers who were supposed to pay up the difference between R30 000.00 and R13 290.00 they tell me no application was received from Modeza Trading t/a M-Hardware to cancel the R30 000.00 and re-instate a new application for R13 290.00, they also tell me they cannot be traced, I feel ******...
