COLUMBIA HOUSE DVD BMG Falsely reported invalid debt to a collection agency. Indianapolis, Indiana

I got a credit card cancellation in the mail saying they closed my credit card account to do a negative collection on my credit. I pulled up my credit and I had a collection for $66. I called the collection company and they told me there is nothing they can do and that I need to call Columbia House. Calling Columbia House and getting a hold of someone is impossible.

I signed up for Columbia House back in early 2003 and I fulfilled my end of the deal by buying all the full priced DVD's. They kept sending me movies after that and I repeatably had to tell them to cancel my account. I told them to cancel my account 8 times and then I finally stopped getting movies.

And now over 6 years later (past our states Statue of Limitations) I get a collection on my credit. The worst of it is that the collection company says this account was opened in Jan of 2009! IT'S BEEN 7 YEARS NOW!!  This has dropped my credit score by 70 points and also caused one of my credit cards to be closed down. I don't know how much more my credit score will drop now due to my closed credit card account.  This has also caused me to get denied for a home refi.  I disputed this on my credit and of coarse they said it was valid.  What's next?  What can be done about this?  How can a collection company report something that is 7 years old and claim that is was opened in 2009/  This is so frustrating!
