Bad service.

I have been a loyal client with Capitec bank for the past 3 years I switched from FNB to Capitec because of FNBs ridiculous service and fees . I have never had an issue with Capitec until today I was happy with their service thus far until today. I app**** at the branch for a credit card and was declined when I asked the consultant as to the reasons why my application was declined they said I don't meet the capitec criteria and that was it no furather information was given and that was it. I have a credit facility and a loan with capitec both are paid on time and up to date the loan would be settled in October 2018. As per NCA it's my right as a consumer to know why I was declined the exact reasons would help, have a laest copy of my credit report from compuscan and it looks fine. I need a credit card to boost my score so I can apply for a bond can you please assist as to why I was declined and assistance with my application.
