Ist mountaingear.com sicher?

I made an order #16724332 at mountaingear.com. They authorized my card with full amount. Next day I got message from the store that they want me to provide payment via wire transfer for gull amount and to pay extra $20 as a bank processing fee. I refused to waste my time and money and cancelled my order. They said that my order is canceled, and the pending authorization has been canceled on their end. But it takes about a 30 days to money back to my card. It's Sept 24 today and I still don't get my money back and can't buy my items in other store. I believe this absolutely inconvenient business if they authorized card with full amount, knowing that they won't accept Visa and will ask for a wire transfer, leaving customers with no items and no money for a month. So if you are an international customer be aware! NEVER have a deal with this store - you'll lose your time and your money."
