My household has received a collection notice?

A collection notice has been sent to our home under a name that both my brother and father share. The client is from Movie Gallery, a now defunct video rental establishment. The amount is for 88.00 dollars. I dont recall my brother ever renting a movie or game from that place, even back when it went went under a different name of Video City. I myself have paid late fees but under my account.

As for my father, I have no knowledge of him ever going into that place to make a rental. He moved out of town back in 1997. I have no communication with him (we are not on speaking terms), so i cant ask about any late fees if he's ever rented their before. This sickens me, because my brother has never made a rental, he has no credit anyways, and why if any of us had a late fee, didnt movie gallery/video city ever gave us any kind of notification before?

I contacted the collection agency and gave them a valid number to reach my father. Again i received a letter from an the collection agency. I do not have an address for him however. Should I dispute this claim with them, seeking proof of what is actually being owed and why? Its been more than six years since i myself made a movie rental and by my account name, not the names of either my father or brother on the collection claim.
