I submitted a support ticket, requesting an increase of my withdrawal limits, on December 6th. I noted that, given my current limits, it would take months for me to withdraw even a fraction of my funds. I asked which documentation they require to enhance my verification level -- and haven't received a response for 40 days now.
I can understand that under the current load of new customers, support times across all exchanges tend to be longer than usual. But 40 days of waiting time is no longer acceptable. I'm not overly fond of public ultimatums, but since Poloniex choses not to interact on any communication channel, I don't have much of a choice:
If I haven't received an answer to my support ticket #554603 within 10 business days, I will take legal action to take possession of my funds currently held on Poloniex. I still hope this outcome can be avoided, but I will not allow Poloniex to effectively hold my funds hostage without an explanation or any sort of response.
I now wait 11 days to get enhanced verification. I did exactly same on Bittrex, same application and same documents and pictures and was verified in 5 days.
