Did you pay using Alipay? If so, are you a Chinese citizen?
I'm asking because I have never been able to use Alipay at retailers or web sites outside China. When I tried to pay with Alipay at Uniqlo in Japan, the transaction failed and I received an SMS explaining it was because I don't have a Chinese national ID card.
I did not use Alipay but the fact that it was available as an option and it was a sponsor heavily featured on materials even inside the stadiums made me think it must be available.
