There is clearly a pattern developing here, via e bay and other media, there have been cases in the papers where scammers, have sold bogus parts that never excist,it was never there purpose to provide parts for a fair price to help others in need,it was just merely a money making scheme, someone needs to coordinate all details of those who have lost out, times, dates amount any user id etc, and take this to the police,as stated there is a pattern, this may not be a civil matter!!1, it may well be criminal,in that case, this need nipping in the bud sooner rather than later, before more people are in this unfortunate position. there is a reason why no one can get in touch with him,you do the maths,but please get this dealt with.
