Losing trinkets and guns from mail

So besides getting screwed out of the Broken Hearts day cosmetics due to profile data corrupting. I now don’t have my Short stick smg and trinket for w.e. reason. I redeemed from mail and then it just disappeared. Please can i get some real help. Its bad enough I lost the broken hearts day stuff due to some b.s. and can’t get that back at all. But now this one time weapon and trinket are gone too. It’s starting to make playing this game really difficult.
