Short story about what happened when you didn't read a contract carefully.

When we came in Canada my husband opened account in a bank. The bank worker said, if he take a gold credit cart, bank will present him a ipad mini. My husband took the gold credit card and 2 weeks ago we received a package. Three months ago my he wonted to change his bank. He didn't read carefully the contract. In contract was written, if you received a gift ipad you cant change your bank during the one year. Gold card's service cost is 30$ per month. After one year he will pay all in all 360$.
