He answered quite fast, basically he says that Yifu didn't refund him and he can't get him to do it (any other group buy in this situation???).
Anyway, in his own words: "you're one of the few people I couldn't afford to refund out of my own pocket and I await Avalon to refund the money they owe me.", which seems to be true if you read yesterday's posts from different people in the group buy.
Same for me, being "one of the few". I am still in (infrequent) contact with Matthew and am just in "wait and see" mode.
