To avoid the delays you have to split your withdrawals. I might've said this on a similar thread but most users that are having trouble on withdrawals have been withdrawing above BTC0.1. You can read most of their cases on the main thread linked above but eventually they get fixed. In your situation I can only say is to wait and even if their support say the same thing always message them once a day. Their live supports doesn't have the power to fix all problems the payments are probably handled by a different team that's why all they can say is to forward the issue.
oh really ? i didnt know that this can help stuck withdrawals but maybe it is ? higher amount of btc takes time to mine that the lower ones . maybe that is the logic behind this trick .
i also got a simillar problem same as op so i definetly gonna try this asap but i remember that every withdrawal have thier own specific fees . oh well , better pay a little more when your in a hurry because time is still the most important of them all
