Collection agencies do not buy debts and collection agencies do not sue. They are hired by creditors to try and collect the money the creditor is owed. The agencies usually try for several months. If they are unable to collect, then they turn it back over to the creditor who then sues, adding collection costs, penalties, court costs, interest, etc. to the debt. There are companies that buy debts (some valid and some not) but those are not the credit reporting agencies, who are not in that type of business.
