I am currently in contact with them since somehow 160 MATIC got "lost" but I need to say I have used them for 3 years without any issues sor far. I will keep you updated.
I sincerely wish you to get your coins back. But I guess that the opportunity to use their wallet and not to lose assets is something about good luck, but not a usual thing. If they would steal all money by all users, they would quickly get imprisoned.
Instead their "partial scam" allows to act like a usual service.
It's like their customers "reviews": you see someone who says "great wallet, i reccomend it" and you see someone telling that he got scammed. And you are like "Well if they would be a scammers there would be no good reviews, so maybe it's just an occasion"

So, there is no chance to rely on positive reviews and also few people or websites may give negative trust to hamper their business and this happens rarely.
