How long have your issues with Poloniex (with your 10 XMR) lasted? Recent months (after Circle-take-over), their supports have been fast
I received a response in 8 hours yesterday.
I think it is acceptable with support tickets. I am not sure about average time of responses of all Poloniex support tickets but I guess the pace has been faster and more acceptable after Circle steps in.
KYC on Poloniex, if I remembered correctly, announced officially and Poloniex users were given weeks to finish their KYCs back in early of 2018. Additionally, it mainly implemented by Poloniex because US government requirements, not solely from Poloniex team. The positive thing with their new KYC verification procedure, after that is all users (including new registered users) don't have to wait for weeks or months to increase their level of daily withdrawal limits to $25,000.
We are at a stalemate with them holding my coins as I refuse to do KYC because they will not allow me to do it without agreeing to their "terms and conditions" (which have me agreeing to waive my rights to hold them liable) which I will not do, so my coins are in limbo unless and until I sue them. I tried governmental legal channels to no avail. Goldmann Ballsacks is not going to allow some district attorney to go after one of their subsidiaries. And for such a small amount its not really worth the effort to pursue currently.
Poloniex users were also given the affirmation that after the grace period, you could still withdraw funds. Just not trade.
Poloniex users were also given the affirmation that the grace period would be x amount of time, right until it suddenly was y amount of time (0).
