Cat S60 worst rugged phone ever

I bought the Cat s60 in May 2017 The phone is just 10 months old and already i had to give this rugged phone in because there was something wrong with its software (continue restarting and overheating) i had to wait 30 days + before getting it back, all was fine it was just getting hot while charging, yesterday n noticed fog in my front and rear camera wich i cant get out.. then my back button stopped working after the back butten my app button stops working.. and now my screen has strange marks on it.. i wil definitely never suggest buying this phone to anyone
