You should have called your bank as soon as they started pulling the "we'll let you pick out anything else" card. Fucking Tightboards did this same damn thing. It took an act of god for customer's to get their money back. We posted warnings about Tightboards and of course they got on and said they were changing things. I told them to prove it, and the same old shit continued. Then they got nasty. Threatening lawsuits and such. We kept hammering them and now they are out of business.
In addition to calling your bank, make sure you contact Visa/Mastercard directly and file a complaint with the county DA in Big Bear. Start lobbing shots over the bow now, don't fuck around. If they are legit, they will take care of this quickly. Judging by your problems, they are probably not legit so get mean with them.
