unhappy Capitec Client

I went to Captive for a loan and they refused to give me saying am in errors with my Standard Bank home loan ,was Astonished how that happened and went to Standard bank to get clarification on the issue, they apologised and explained it was an error on their system as I had switched banks , so they gave me a letter provide as prove that I am not in any errors or omissions. Then Capitec still couldn't help me and said am in errors. I then contacted CompuScan Credit Bureu to understand what's going on with my credit. They sent my credit profile it had no errors and they advised me that Capitec Hasn't updated my credit after the mistake made by Standard bank on the month of September. So I was again given a letter to provide again to Capture and I was still not helped. I then called their contact centre and the lady said she knows nothing about it and gave me a number to call , which I called and was told there's nothing they can help me with . So your my last hope as my name is not cleared on their system only and they refuse to help me
