These scammers are testing the V2 exchange. I think they will close all accounts of the old version, and as if nothing had happened, they will continue to deceive further.
I almost missed noticing your updated images and on those notes, I'm going to tag their representative in here but in your "withdraw history SS", it's not clear if it belongs to their platform [you might want to upload a better SS that shows also the URL while censoring other important information for privacy].
