My total portfolio from Bitpanda is emptied, no answers from "support".
What choices I have?
It's very unlikely that your account got emptied without any traces. Check your transaction history, if you find that funds got withdrawn to an address that you don't control, then you might have been hacked.
If you're sure that it wasn't the case, then here is the fastest way to get a response from them:
1. Write in their
announcement thread as suggested above.
2. P.M
TwinWinNerD (he's their representative) and link him to your post in their topic.
Make sure to explain the situation with as many details as possible in your first post to avoid any delays.
