Hey there, just a tip, if you're going to accuse anyone or any entity of scamming you out of your money or coins: documentation beats conversation. If you're accusing Poloniex.com of scamming you, you need to provide screenshots of your transaction. Your email. Your account on Poloniex. etc.
This forum is flooded with a lot of people who create accounts for the sole purpose of crying wolf, only to find out that their transaction was stuck or there was a delay in processing their transactions. Not saying that this is the case for you, but these people often don't return to update their threads when their issues resolve themselves. That's why you'll see a lot of skepticism from people in the future.
As I see more and more accusations rising against Poloniex, I've submitted a withdrawal request to pull my (small amount) of coins from the site. These "hiccups" don't look good for Polo, but hey, that's how the cookie crumbles sometimes.
For the record, I don't trust any exchanges, and don't store more than what I'm willing to lose in any exchange. Not sure if you're familiar with Mt. Gox, but a quick google or wiki search will show you what happened with that popular exchange years ago:
https://en.wikipedia.org/wiki/Mt._GoxI wish I could say I'd like to help you, but unless you provide more proof, you're going to get a lot of "suck it up" responses, or more responses from people asking to show some proof.
And yeah, like @shdvb said above, move this topic to: scam accusations (
