Order cancelled

I ordered a coffee machine. When I checked up on the order on Wednesday evening I noticed that it had been cancelled. Then when I searched for the product I couldn't find the exact product I ordered. I presume the order was cancelled because the product isn't available, although the orders page does not indicate a reason. I did find a different version of the product which looks like it is functionally the same and customer support suggested I order that instead, but the price has changed. I've had no further response from customer support. I'm buying this as a gift, so I'd like to get this sorted out as quickly as possible.
