Scam problems are out of my range (i can track ip tho, but cant check trades nor restore items), and there is very limited amount of ppl an do it. If u comapre it to amount of players and tickets which are submitted daily, the result may give u a headache. So there is nothing u can do but be patience and wait.
About the investigation itself it depends on the case, mainly if account was shared. But i have no idea how admins will treat this case since its ur own stupidity

sorry to say that. So once again, u just have to wait.
And beside if u get confirmation that ticket was submitted then obviously its there, it will not disappear.
