Hi, I will be happy to advise on this issue
I am sorry you and your grandson had to experience such a thing
what device was your grandson using to play the game on?
Home- PC Laptop
this user will need to be reported directly to Sony Entertainment so they can take the appropriate action against them
If you follow the link here that will allow you to report them as a rule breaker
Then please give me that info so I can contact them directly
Sorry it just came up.....
that's ok - chat was a little slow
you are welcome
let me know if you need anything at all
