I'm in the US now and I called up I-C Ambassador customer service and the first thing I learned is that all calls to Ambassador service are routed to the Phillipines.

They said to fix the problem I would need to fax the hotel receipt to them. I said it's pretty expensive for me to send a fax to the Phillipines. They said no problem, you can fax it to London. I explained that this too would be expensive. However I was flattered that they think I'm even capable of sending an international fax. Most Americans wouldn't know a country code if you hit them over the head with it.

So I asked them to call the hotel and get the receipt from them. She said that if I don't hear from her within an hour, to call back. I said I doubt you are going to find out in an hour seeing as how it is 3:30am in Beijing. Maybe I'll try back tomorrow.
