eGay were do i stand??

[Chris_90]

So i sold i pressure regulator on ebay on the 6th of november i posted it on the 7th first class, i have an e-mail a week later saying the guy has not received it. So i have been to the post office to see what they say, they said i can fill a form out and the will start searching for it after 21 days of the item being posted they may compensate me but its not set in stone they will. After telling the buyer this he will not take no for an answer i have told him to open a case and he is refusing to open a case?? Not sure why.... so i have told him to contact ebay he will not do this either. I contacted ebay they said i have gone about this the right way. The guy is now threatening to leave negative feedback, Now i have done all i can do there is nothing i can do about the item getting lost as far as i am concerned i have done every thing the right way.

What can i do to solve this problem? I dont want to just give a refund because im with out my item and without my money. Also i dont want to get negative feedback...... Really putting me off ebay now as never had a problem before until now :-(

On the other items i have for sale i have now put ""Please note postage is for first class post i will not accept any loss or damage in the post, i will happily post special delivery (less likely to get lost) but you must pay the extra postage!"" spoke to ebay about this and they said its all ok as its the buyer has to read the description before buying. So hopefuly i wont have this problem agin.

Any help welcome
