Closing out delinquent accounts or those with a history of late payments can also help, as long as you've paid them off in full. Because history is important, if you do decide to close a few more accounts, close the newest ones first. The length of your credit history is 15% of your score, so even after you've paid down your balances, keep your oldest cards open. Be sure use these cards to make occasional purchases (then pay the bills in full), so the card company won't close your account for inactivity.
Your best bet is to call and ask to see if they can put you on a payment plan where you can afford to pay them (even if it’s just the bare minimum a month) or if they will possibly settle for less money. A tip: anything that has your name attached (banking account,utility bills, credit cards, anything you finance, student loans, medical bills, car loans, home loans, your apartment, etc) that you miss a few payments on or don’t pay at all can be reported to the credit agencies and sold to collections companies.
Write a letter to the specific credit reporting agency that shows the falsehood, whether it is Experian, Equifax, or TransUnion. Explain the mistake and include a copy of the highlighted report along with your documentation. Although certain bureaus now let you submit disputes online, it’s not a bad idea to send this letter by certified mail, and keep a copy for yourself. The reporting agency has 30 days from the receipt of your letter to respond. The Federal Trade Commission provides advice on contacting the credit bureaus about discrepancies. Here are the contact numbers and web sites for the three credit bureaus:
