Like Bill S from 3/27/21 I had exact same thing happen. First transaction went smooth and quick on 3/23/21, now second on 4/11 they start their crap. Take your coins then nothing! When you email about transaction, they ask for pictures, then videos, then transaction picture, then transaction hash text, then exchange ID, then moree and more BS. I too had to contact, Coinbase, Youtube, local police and now FBI cyber crimes department. Stay away from these scammers!
