I, too, can not find my transaction on cryptofresh.
I sent the BTS from the exchange to my wallet:
"Complete: Error BTS 135630.42591800
2017-05-19 14:43:59
Address: serg-k"
I was wrong in the address. This address was not registered at that time. Noticing this, I registered this address, but BTS did not receive it.
From the balance, the money was written off, but I did not get it.
I wrote a Poloniex tech support right away, but they did not answer for two days.
