Collection agency, Credit report

What can collection agencies do?

I pulled my credit report, and one collection agency has taken bills (med) that are at least 5 years old and grouped them into one account, making them stay on my credit until 2012. It was my understanding that it would stay on my record from the date of first delinquency with the original creditor, but it appears that now that is not true (according to what I am looking at).

Also, the original balance is on there, but it has escalated to $600.00 more than it originally was. I have disputed it, but would like to see if I am right or wrong on the above paragraph. Thanks.

Check the statute of limitations for your state here:

Every time you make a payment the clock starts all over again…. You’d be surprised how many people try to collect money after they’re past the statute of limitations. From www.creditinfocenter.com
