Hello!
Tell me, please, has anyone worked with the Garant.pro service? They position themselves as intermediaries (like paying through a safe) when working remotely with customers. Here is a link to this resource - garant.pro/. How to check if it's a scam? And what kind of reliable service safe would you recommend for work, taking into account the fact that customers can be from Ukraine, Russia and Belarus?
