How do you deal with inexperienced players who refuse to take your advice?

[Mizunoko]

This question of mine stems from something i experienced recently. To sum it up, basically our seiryu ex pf was filling in the role for the OT we had that just left for sleep. Once we got our new OT slot filled I started off as main tank, we got to the first cursekeeper he provoked like he was supposed to and i shirked him (tank swap mechanic), and then for some reason the tank swapped aggro right back to me and we all wiped. I tried to be patient with him and explain that common practice is to wait until the next swap mechanic to swap back, and by doing what he did he ended up wiping us (regardless of us all being a bit upset about this we tried to be polite about it). Instead of just taking our advice and doing things the way we normally do/did when we had the other OT he proceeded to insult me and try to blame the situation on me saying i didn't know how to tank. The tank we had before this new one was perfectly in tune with me and the party in when he was supposed to provoke, shirk, shake it off etc, but this new one just seemed like someone who didn't care about inconveniencing others and wanted to jump into something he wasn't ready for.

As a veteran player i would like to think i have a good grasp on most classes, especially tank since i have main'd it for so long now I don't feel the need to defend myself as a veteran so once half the party broke up and he left i simply blacklisted him, i don't really want people who make drama like that in future pf's of mine. Anyway not to get too focused on the drama of it, my question remains. How do i deal with these types of people. This has happened a few times in the past over the 5+ years i have been playing now and even though it is rare it is still a somewhat irritating situation to come across and i am trying to find any ways to maybe word my advice so it maybe sounds more sincere or perhaps this is just a type of encounter that is inevitable? (please keep in mind any replies would preferably be about my main question as the context is just an example of why i have resorted to asking this question in the first place) I am sort of an introvert myself so social interaction isn't exactly my strong suit. Any advice would be greatly appreciated, thank you.
