Survey emails don't go through customer service. Try replying to the initial auto reply instead.At this point my faith in Epic to even support this game is nil. I contacted their support regarding whether or not they would have cloud saves(something I love about Steam) and if there were going to be any install/activation limits(never know even if it seems unlikely). I got a generic email with a link to support for Fortnite. A few days later I got a survey email regarding their response and I repeated my questions along with mentioning I wasn't asking about Fortnite. That was last week.
Not happy with their handling of 2 simple questions or this exclusive, so I'll just wait until it comes back to Steam. You'd think such a small company trying to make a big move like this would have greater care for prospective customers. Not a good way to start.
My only quess is they are currently inundated with a million entitled gamers asking them when their brand new store front will have ALL of the features that the other Store front added over a 15+ year time-frame.
Give it time, nothing happens overnight.
