no payouts!

I started ZEC pool at after switching from some other pool in hope of better returns. My workers are doing good and earned zec beyon auto-payout threshold i.e. 0.1zec
Now I entered my zec wallet address (from in my coinmine account settings and saved it. It did shows saved but on next login, there is no wallet. Same thing happens, if i try putting my wallet again. Operator is not replying my support mails. I begin to suspect if it is a legit pool!!
There is no option in account for Manual Payouts. My coins are stuck there. Can someone please guide me on how to resolve this issue.??

Has someone out there got payouts from zec coinmine ?? please help and advise if I should stay away from these guys??

Many thanks and kind ragards
