I once received a tube type amplifier that the seller just stuck the thing in a box and shipped it to me.Needless to say it
had a rattle noise when I picked the thing up.I knew the tubes were broke without even opening it.I took it back
unopened and filed a claim with U.S.P.S..I had to give the package to them along with a receipt of my transaction.
It took over 6 weeks,but they sent me a check for the price I paid,minus the shipping.I did try to contact the seller who
never returned my reply.Thus I gave him a big negative and why I did it.I wish I could tell you exactly why U.S.P.S.
paid,but I can't recall why..I would contact the seller if possible,whom will probably say not his fault.Then the post office.then
PayPal if you paid through them..PayPal insures your purchase but you have to go through their dispute system to do it.
Ebay also insures your purchase..And they also have a dispute process.Lastly if you paid by credit card you can file a chargeback.
Putting the charge back on the seller.The sellers fault for not insuring the package.
