Unfortunately, their representative hasn't been active in the forum and many customers has complained a lot about long withdrawal time and being unable to reach or having poor customer support.
Going through their main thread on the forum, here is a latest info about withdrawal:
I haven't really been around the forums except sporadically but I'm one of the older members of FBTC. With that said, after reading concerns, I set up a test withdrawal. I'll report back when/if it goes through.
That would be good, I did a w/d all on a few remaining sats last Thurs Aug 14, that went to manual review where it still is, not really expecting anything.
I think the last few reported successful withdrawals were Aug 5
By the way, this is not the right board for this complain, you can move it to the Scam acquisition or this will be done by moderator.
