Resolving your credit problems starts with checking your credit report through your local credit reporting agency. If you find a mistake, bring it to the credit agency's attention and, if they will not remove it, you have the right to place a letter in your file explaining your position. If you cannot obtain a credit card because of past bad credit go to your local bank and apply for a secured credit card. Under these plans you deposit money into an account equal to the amount of credit you will receive. As long as you pay your credit bills promptly this will help provide you with a good track record for future credit applications.
Good credit takes work.
