I applied for a CapOne Quicksilver Rewards card. I got declined. I was told it was based on my credit report from TransUnion that my length of credit history is the cause of denial. I have had my 2 credit cards for at least a year and 2 months now. Always in good standings. My question is how much positive credit history do I need before I’m approved? Also, is there someone I can call about this to get the decision reversed?
