My first dealings with mmoga.de went less than smoothly
The phone ID verification failed, then we went through the whole passport photo shenanigans that has already been described by many reviewers
Started to think this was gonna be a scam, but I felt I was already committed and would play out my hand and see where it led. I paid with Paypal so I figured I have some basic recourse if it all goes south
After some back and forth email with the firm's verification department, they eventually were satisfied everything was legitimate, and delivered the code (about four hours after the paypal was sent), saving me around 45% over Steam or Epic prices
So yes if you want easy and smooth then the process is certainly not that, but they did deliver on their promises, I can't fault them there
Act like an adult in your communications with them, you will probably get what you want... I found them to be reasonable although the order process is kinda ridiculous. Obviously any info they potentially harvested from seeing my ID would be freely available across my general online data points, social media etc.
Your basic info is nothing secret in the modern world unless you live in a cave on a mountainside with no data connection
