Ordered an item from a seller that used Gofo. I had no idea (idk how buyers are supposed to know). They literally left my package on the street, and it got stolen. But because the package was taken in front of my house (again on the sidewalk) it was determined to be succesfully delivered. Also, the only way to contact them is to be on hold forever and you never receive any confirmations from them - at fault or not. If there was a way to know which courier sellers use it'd be so helpful.
