I got an offer for a Wells Fargo Platinum Business Visa with 0% on balance transfers until paid in full. I called and spoke to three different customer service people confirming it. I went into the bank to confirm it and apply. I got the agreement and read it. Nowhere did it say 0% on balance transfers until paid in full.  I received the card and the paperwork with it said 0% on balance transfers for six months. I went into my local branch where I’d applied and told them to confirm it before I wrote the first check. They did. It’s 0% for 6 months. I showed them the original envelope of the offer saying “0% on balance transfers until paid in full.” They were embarrassed. I asked to cancel it. They said there’s no fee to keep it if I don’t use it. What about the “inactive fee” mentioned in the agreement? No, there’s no fee if I don’t use the card.  We’ll see.
UPDATE: 2-14-14 I received another one in the mail!
