Last summer it was taking two months, and the exchange is probably more overloaded now than back then.
Congrats! I understand your pain as it takes me 2 months for the verification as well. Hope poloniex can improve on the customer support area since the troll box moderators are assigned to support tickets.
I still waiting over 2months for level 3. And my balance is 0.4btc left there. I now prefer to transact in other exchangers. makes me feel better.
Although today's support response times are completely unacceptable I suspect they will soon get much worse because all legacy accounts will soon need to upgrade to more stringent KYC verified accounts.
