Swap history

felto1942 swapped his car for mine. I have emailed and emailed and he has not replied back. He has put me in a very difficult situation as i could have swapped with someone else and it was advertised elsewhere and would have been bought 10 times over but i refused the buyers on the understanding that this man was swapping. He has emailed me few times but nothing since the swap. This is not very good for ur site and shows that the rudeness and ignorance of people. I know he has been on site as it tells u when they were last on. can u advise me on this now.
