Anyone else having trouble withdrawing xmr from mintpal?

I know about the vrc issue, but I withdrew 3000 bc and .7 btc no problem but now my 266 xmr withdraw has been pending for almost 24 hours, I have opened 2 support tickets and gotten no reply.

Time to jump off a building or no?

Im sure they are in crisis mode over at Mintpal so not suprised to hear some withdrawals are slow. Ive withdrawn my last coins from there and it took a while.

May i join the club of stuck Mintpal withdrawals?

It's a fairly nasty situation.

A POS coin is stolen from an exchange via a direct SQL injection. (allegedly)
The coin dev chooses to roll back the blockchain to avoid a single owner having 30% of coins. (Important ina POS scenario)
Exchanges freeze the coin as the blockchain is rolled back and the coin forks.

Nasty.  Bad bad implications...

Interesting analisys but it might be true

do you mean your xmr?

Is there a way to cancel a pending withdrawal?

BTC withdrawals are working fine so I was thinking about trying to cancel the withdrawal convert to btc and withdraw the btc and buy the xmr back from polo. I already confirmed through email, is this possible?

^All of the exchanges had delayed XMR withdraws up to 12-24-48 hours from time to time (their daemons stuck, etc.). Most probably they'll get to your ticket (their ticket system should be overload now) and you'll have your withdraw processed.
