I also lost money on their service. The website does not work, nobody answers on the discord channel ;/

That is why I now investing in projects in which the coin developer himself offers services.
A good example is the Teloscoin.
Dev coins offers the peertoro service

just like STAKING / POS .

Maybe it will be an alternative.
