I put this as politely as I can..... I've never seen eye to eye with Gordon in the past so I can't say I'd ever try to buy something from him.
You can try contacting him through the Robotrov group on yahoo http://dir.groups.yahoo.com/group/robotrov/ I don't think he's been active on there since around April but maybe the email address he uses there will be good still. If it's not to late I'd just put in a claim through ebay at this point.
Try this... make a new email address with a total random name (gmail or what ever) email him from his site but don't mention you are still waiting for something you payed for.. instead expressing interest in his product that you would like to purchase and see if you get a response that way. If you don't ... then maybe something happen to him... if you do... I'd say he took the money and ran.
I paid via paypal. But since i was too nice and gave him till aug4 when he said it would arrive, I can no long file a claim with them. Past paypal's time to file.
And since his ebay account is gone they cant do anything either.
Purchased the Rov Asia in march and it arrived promptly, pre tested and all. Since then we have been trying to make a significant purchase (complete rov) from Duncan but he seems to have vanished and didn't reply on any inquiries. Don't think he is a scam but I have been wrong before.
I did get totally scammed by westbourne models in UK that simply refuse to deliver what we payed for. Don't know the UK legislation for online purchases but we will probably have to go to court. Anyone else using this company?( you UK guys)
