HSN Home Shopping Network Unauthorized illegal credit check. Nationwide

 I placed an order online for a laptop and chose the flexpay payment option. I entered my credit card number. At no time did I give permission for a credit check, and I did not enter my social security number. HSN placed a hold on my checking account and then cancelled the order. I received a letter from HSN that said that they had run a credit check on me and were declining the order. No one could explain how they received my credit report without my social security number and without my permission.
