OP if you are serious about getting their profile tagged here and a flagged getting made against them, i think it's wise to make a full scam report following the right report format as suggested and remember to include proof of payment/transaction. Community members will help you tag them.
Looks like someone else got scammed too
They say they don't do KYC but then after accepting my 2.6 BTC deposit, they decided to keep it and claim it is because they need to do KYC. There website says they don't do KYC and the comment above says it. Even if they did, they could simply not do business with me and refund my money. Instead as you can see in the review here from alex brian here they are choosing to keep it:

Quickex, please refund my BTC, exchange: afba_1fedefbd-42d4-4eb1-9de1-92acf9a25199. I will happily update this once you return the funds. Until then, I recommend everyone stay away.
