Wi-fi calling not working. LG free battery promo gave my invalid date error.

Well, for whatever reason, my wi-fi calling will not slide from off to on. The screen flashes briefly and calling remains off.

Also, when i went to submit my application with LG for the free battery promo and used the date of 4-1-2016, i got an "invalid date" error.
