Was the withdraw small, say a couple hundred dollars? It is common they will let you withdraw a very small amount to try and make the platform look real. If you try to withdraw more than $300 they will not let you do so.I successfully got my money out of HKEXpro! I did not want to have money sent to my bank, as I didn't want to give up that information, so I had it withdrawn and sent to my coinbase app, via bitcoin. The funds were frozen for about a day, but ultimately got my money off of that platform.
