Wells Fargo Credit Card Complaint

Wells Fargo Credit card department,

Advertising and marketing Texas

Wells Fargo is having a representative with a furniture company who is misrepresenting the terms of the finance agreement. We were told the terms were no interest for one year and after a year interest on the remaining balance. So after a year we were charged interest on the balance we had already paid. I am sure it is in the small print, but how can they have a third party define the terms when they benefit from the purchase.
