I applied for instant credit at a local chain store in person. The clerk went away and came back after about 5 minutes and told me I was turned down. It's been a while and I have never received a letter from the credit issuer HSBC. I was wondering how long they have to provide me the reasoning and source of credit information that led to the denial.
Typically, the lender will send you a notice of denial. This letter should include your rights under the Fair Credit Reporting Act that you are entitled to know why the denial was issued. However, the burden is upon you to make the request which is usually within sixty days of the denial of credit.
Send a letter to the company that denied you credit and request the reason why. They are duty bound to provide you with the reason for the denial. If they do not, then this is potentially a violation of the FCRA.
This previous answer assumes they looked up your credit report. They may have used a service that lists people who do not qualify for credit based on past defaults. If the company used internal information to their company and did not access your credit report then they do not have to tell you why they denied you even if you ask them.
