Fraud with my SS#

I was in the middle of closing on a home and we had a credit inquiry from Dish Network.  Most mortgage companies will tell you not to open up any accounts.  We have never had Dish as a provider.  I was very upset that someone was inquiring about our credit during this home purchasing process.  I called them up and asked how they were able to pull our credit without our consent.  No clear answer was given and finally the sent me to the fraud division.  They asked for my SS# and said I had an account with them.  No....I have never had an account.  They said there was a balance due.  I said ok, "if this is my ss # attached, what is the name on the account?"  They refused to tell me.  I was told that I would have to file a police report, file a complaint with the trade commission, contact all three credit bureaus and then fax them all this back up documentation.  ARE YOU KIDDING ME!!!  On top of that, they would not talk to me about "my supposed" account because the name on the account was not obviously mine.  I am livid and if I have to spend the rest of my days talking people out of going with Dish Network, It will be much easier than what they are asking me to do.
