No one from bitvest has contacted me and I don't recall using any email address to sign up so I don't know how they would contact me to ask for KYC. I tried creating a support ticket just now.
So, you just contacted the support despite your withdrawal pending for a week and I suggest you to wait for 48 to 72 hours from the moment you contacted their support and if you still haven't received any response then your are free to create a thread about this in scam accusation and see you will get response after that.
LL hasn't been active for a week now, so you may get a response what is going on if he comes online in the meantime.
