Someone else with the same name owes a bill. Can we be turned over to the credit bureau based on the name?

A collection agency has contacted us by phone and by mail several times about a debt owed to Dish Network by someone else with the same name. They are threatening to report us to the national credit bureaus. The debt is $179.65; they want us to pay $89.83. The bill was incurred about 9 years ago. We did not have an account with Dish Network at that time. We used DirecTV 9 years ago. We do have an account with Dish Network at this time, and have had it for about 4 or 5 years. Our payment history is excellent. They want us to pay a bill that is not ours. It is a different account number and a different service address, but the name is the same (and in the same town as we live in.) We have been married almost 38 years and have excellent credit. I am worried about this bill tarnishing our credit. I cannot remember if we were required to provide a social security number when we got an account with Dish Network. I don't think we were. Can they turn us over to the national credit bureaus for a bill that is not ours because the name on the account is the same? Don't they need more than a name to do this?
