I attempted to purchase a lift ticket and rental combo for my son to ski with his friends the following day. I entered all my information and submitted the order and got an error message. Some general message that there was an error and the order didn't go through. I tried again. Received same error message. Then my credit card company informed me by email that I was charged twice for the tickets! I never received any receipt or anything so here I thought I had been charged twice for tickets. No customer service was open at the time so I had no way to find out what happened. The following morning I contacted the mountain and they told me that I had to contact Liftopia. I didn't even realize I had purchased on Liftopia. I thought I had purchased on the mountain website. The "customer service" person told me that the charges didn't go through, they were just requests and they would be removed in a day or so. The reason for the error messages is that their system is very "finicky" and often if there is a tiny error in the billing address or zip code, it doesn't go through. But the error message never said that! I would've played with it until it works. I can't believe a company that does all online commerce doesn't have a better system than that! How about a specific error message so I could've tried again? So my son was at the mountain with his friends with no lift ticket and had to purchase for the full window price because their system is crap.
