Does Any One Know This Collector

Dear friend!
5 years ago , I met this guy online, we exchanged emails. he had sent me a list of India mints he needed and I insisted for small exchange first, but he sent me images of lots of elephant stamps and promised them to me, I too sent a big lot and once I informed him that I had sent him the stamps, he stopped responding to my mails.
Few months later I sent him a letter with acknowledgement receipt, I got the acknowledgement receipt back , but still he didn't responded.
This incident was a real blow, made me think twice before sending some mails, I reduced sending mails.. and now after few years I am back to exchanging, started exchanging small lots with new swap friends.
am attaching the photo of cover I had posted to him and am still searching for this guy.
