Malaysian GP tickets via Gootickets

Does anyone know if Gootickets is trustworthy, like is it an official resale website for F1? I was considering going to the GP but when i seen the prices i thought it was too much and then they eventually sold out. I then seen some people mention Gootickets and when i checked for myself i managed to purchase the same ticket for a bit cheaper, but im not sure if they're legitimate or not.
