According to her listing, she bought 6 umbrellas for her wedding, and is selling 4 of them. 2 single listings, and the last being a listing for 2 of them. First 2 had postage attached, the other 2 were pick ups. Im guessing it was one of the first 2 that is the offending listing.

I think there is possibly more to this because no one is going to get restricted for one refund.
