How to complain against GM, to which country ..  Hong Kong , or Iceland.

Their bank account in HK but they claim they are an Iceland company .. 

we need to collect all information about them from now .. we should not allow them to hide.

I am not taking about the real business and the impact happen to all users because of halving .. that impact is uncontrolable .

but There is a case that GM did not providing some user their coins ..

even the phone they remove from their website ! ! !
