Ok, a response is a good start.
Firstly and above all, actually declaring how many BTC I received is pretty unprofessional. I can't believe for a second that you actually thought i wouldn't mind about that.
Please edit your post. (If a mod can do it that would be great)
Secondly, I have tried emailing, and PMing you and your team. It's not just you so don't get all defensive about it it's just that you popped up on here. I actually received an email from Richard Caetano on the 13th August, (you, Davout & Grandval were all copied in), stating that this wallet had been confirmed as emptied out by the hacker. I replied immediately, (and then again after a week or so when i received no response), but still no reply. I did consider ringing you but thought that might be a little inappropriate.
Now you are suggesting that you have no proof I deposited the money. How about all the same proof that i used to prove all the other wallets that I held with you were mine. Nothing was different with any of them. If i proved that the others were mine (which i did as you returned the funds), then i proved that was mine also. Now if you have agreed that the hacker cleared my wallet it's all very simple.
My suggestion is that if there are funds left over from the payout process, (which i am sure there are based on the fact that I am sure I am not the only one who lost a URL during their time using instawallet), you should repay me. Asking me for more cryptographic proof now is a blatantly obvious way of trying to make it impossible for me to get what is rightfully mine.
Please enjoy your 'vacation' but if you or your team feel like responding that would be ideal
