When many began GM accounts around 2010 it was more simple with lower fees. It was perfect for travelers who could "set it and forget it". At some point that change, seems like around 2020. Fees got ridculous with notification and they began demanding more documents that those traveler types don't have.
You will be lucky if you can ever get your money back from this place. They demand reverification of documents that are near impossible to get for the types of folks that GM was originally marketed to.
At this point it seems like it might be a legit ponzi.
