I recently made a purchase from a vendor that I had to place the order THREE times before it was successful! The first order was cancelled despite my credit card being charged. Then the second one was cancelled for non-payment (even though they actually had my money) since the large charge was a duplicate and the bank wouldn’t process it. Then when I called back again to get things fixed, they had the same problem placing the third one; but they finally figured it out. And these difficulties were despite making every order over the phone with U.S-based customer service. I’m sure it wouldn’t be this hard if they weren’t the only source of the items they sell.
