"We appreciated your love and effort towards sports in our country. You, an ALL BLACK, have lowered yourself and your glory when you verbally abused the referee during the game.
"I would like to remind Malakai Fekitoa that the youth of Tonga look up to you as a Ha'apai male, ALL BLACK. However, because of your atrocious behavior towards the people of Tonga, this tournament has become unpopular, so no referee would be involved in refereeing this event."
New Zealand Kaniva Pacific, a local Tongan media source, is reporting that Fekitoa responded to the allegations with a Facebook post that claimed he would no longer try to help his homeland.
He also alleged the referee was drunk.
"When I looked at the media regarding this, it came to me that Tongans put down other Tongans. So the immediate thought that comes to mind is that this is the end of any planned programme to help people of Ha'apai and Tonga, for that matter.
"I'm out!"
The Facebook post quoted by New Zealand Kaniva Pacific is not publicly visible on Fekitoa's account.
The Herald has sought comment from Fekitoa and his manager.
