LTC transaction ID not not found

I transferred LTC from poloniex to bitstamp on the 20th of June, I got a transaction complete message and also i transaction id, but i haven’t received my LTC at bitstamp. I tried checking the transaction id on litecoin explorer and no record was found. I have opened a ticket with poloniex but they haven’t responded till now. I have sent 2 additional replies to them but no response from them. Am beginning to freak out.

I have the same problem.
Poloniex, status complete, no results in ltc explorer.
Who can help me?
