Ticket # 329459 - processing since 6th June (101 Days)
Maidsafe deposit never arrived up in my wallet.
I raised one other ticket in the hopes to maybe create some urgency but haven't heard a peep.
I'll report back here if I ever have it resolved.
I had my ticket resolved a couple of weeks ago, in total I had to wait about 10 months. They clearly don't have a very efficient system in place over there.
Good luck to you all, make a thread on the reddit poloniex page, I'm not sure if this helped but mine was resolved not long after I opened one myself.
