Cryptocurrency transaction are irreversible, so for starters if your wallet have been compromised by scammers there's nothing the community or you can do to retrieve back your coins. You haven't provide the deposit transaction ID or address so your issue can be properly access. For now the possible conclusion is either you're using a phishing site or downloaded a phishing wallet without knowing in this case you have to uninstall the wallet, clean up your device and download the correct wallet from the right source or if you're using a site like MEW make sure you're using the right site

For more precautions, you should create a new wallet and send all your coins there as your previous might have been compromised that's if non my possible conclusion above are the case.
