Alright guys remember what I always say you can lead a horse to the water but you cannot make it drink! Rather than focusing on someone that does not want or care to have your help, simply move on and find someone that does.
That's their snake they are free to keep it the way they want and ignore issues and not listen, going back and forth is not gonna make any difference if someone is not willing to listen and will only increase the negativity which will eventually lead to the thread being locked.
In other words pick and choose your battles.
