JPMorgan Chase Credit Card Complaint

JPMorgan Chase Credit card department,

Balance transfer fee California

Registered for a credit card with a pre approved letter. The card was mailed to my old address and took time for it to be forwarded to my new address. I inquired about a balance transfer and over the phone they told me there is a 0 % fee. I just looked at my statement and there was a $100.00 fee. When I called them they claimed that the first - days there is a 0 % balance transfer fee and not for the first year as they informed me over the phone. I feel like I am being taken advantage of.
