If you have any records..emails, and phone records ...Phone Visa and tell them your problem, if the Visa is through your Bank go into the Bank. I know Visa can cancel the transaction. I friend of mine was trying to buy a rotating assembly from a company in CA and after 2 months of pain and suffering he went into his bank with a record of phone calls and emails and they reversed the transaction .. I even phoned the company and asked for the same assembly and they told me, it would be ready to ship in 5-7 days. As soon as he realized Visa Nuked the transaction he was on the phone screaming, my buddy asked him flat out, "When will it ship?" and was told 5-7 days. Remember Visa is there to help you.
