As to the seller's lack of communication, IMO there's no excuse. There are online translators and forums where one can get full messages translated. Plus, the seller could ask anyone to help him/her reply to an email. In any case, if the language barrier is so severe that the seller cannot communicate with the buyers, then that seller shouldn't be doing international transactions.
