Wells Fargo Credit Card Complaint

Wells Fargo Credit card department,

Credit card protection / Debt protection New York

I bought some furniture from - furniture and I was about to pay the whole balance upfront as I had the money at that time. But the sales person insisted to open the credit card with zero interest for 12 months. So I have applied for the credit card. He has mentioned that I have to pay interest if I will not pay off the balance in 12 months. He did not tell that if I do n't pay the balance on the whole amount of the furniture. So I paid off $2400.00 in 12 months and remaining balance was $1000.00. Now they have charged me interest charges of almost $900.00 saying that its accrue interest on the whole balance. According to the customer service, that is written in terms and condition that accrue interest will be charged.However, when we opened the account sales guy did not mention a word about the accrue interest.
