Two days ago, I transferred the xem to Bittrex and did not get a deposit. What can I do? Is it possible to get lost like that? Support has not answered me yet

You should check your address is correct, and then check the transfer process, you will result
Adress is correct. How to check transfer proces? Send from Spectrocoin to Bittrex
Did you also add the correct message?
The address alone is no enough if you send to Bittrex. They have one single address for everyone.
Yes i add message. Probable that the reson I cant see nothing on-

This is why it's recommended to never send directly from exchange to exchange. If you can't find the transaction in the block exploer then Spectrocoin might not have sent it. Also, Bittrex does not currently support deposits from multisig accounts so if Spectrocoin uses multisig that could also be the problem.
what can i do? my money must be somewhere??
Guys, I am missing 8000 XEM. I made a withdrawal from Poloniex to my Nem nano Wallet 99 days ago, ticket #472121. Firstly 47 XEM as trial and it worked fine then 8000 XEM to the same wallet and 8000 XEM is gone. Poloniex posted transaction as complete on my deposit and withdrawal page with non-existent txid on NEM blockchain. Submitted ticket right away and updated it many times but nothing from them, Poloniex just keeps ignoring me. I am becoming desperate, really dont know what to do. Does anybody from NEM community have any influence on Poloniex Support Center. They cant just take their customers money and ignore them like nothing has happened. Any advice please help.
It's very sad to hear this. For a long time I have been trading at Poloniex, but there were no such problems. It does not seem that this is only your problem, it is worthwhile to us all to think about the free trade.
