Hello.
We have checked your ticket. Since you placed your ticket publicly and thus violated terms of services, we also decided answer to you publicly.

VSM - amount must be an integer (we have warning on withdrawal page), you used decimal, that is why 8 of your withdrawals get stuck.
GOLOS - instead of wallet, you used memo, that is why 2 of your withdrawals got stuck.
LEO - you used incorrect or non-existent address, that is why 6 of your withdrawals got stuck.
EMC - incorrect work of node, 1 withdrawal got stuck.

All in all, 16 from 17 withdrawals got stuck by your own fault. Any of such an incorrect withdrawal requests may be lost, we have a proper warning of this in withdrawal form. So you must be carefull, since we can not return all erroneous withdrawals, it doesn't depend on us sometimes.
