FixedFloat exchanges sadly continues with scamming their own customers

Today I saw member Onat posting that he lost 1.9 BTC and they didn't release coins to him for more than 40 days!
I really don't understand why they simply not refuse some coins and return them to customers.
Accused service: FixedFloat (ff.io)
Amount: 1.9 BTC (1.4 BTC + 0.5 BTC)
Date sent: December 11
Status: Funds not released after 40+ days
I don't understand why would somebody send 2 Bitcoin to an instant exchange and especially to FixedFloat, that has so many issues. Instant exchanges are a little bit like a gray area to my mind because the way they regulate is a little bit off. This is basically a legal crime. Seize whatever amount of money you want, no problem.
When they seize money, where do they keep it? What do they do with that money? I bet they use it the way they wish, like, it was yours yesterday but today it's mine. I have never heard any government approaching to such an instant exchange and asking them to release the funds to the government. This is what needs to be regulated but instead, governments give green light to crime under the useless license.
