Samoa coach Viliamu Punivalu plans to have another chat to the head of referees following a frustrating end to day one at the Wellington Sevens.
Samoa beat Kenya and Tonga in Pool D before a letting a second half lead slip in a 15-12 defeat to Australia.
Coach Viliamu Punivalu says the 50/50 refereeing calls are still going against his team but admits they were guilty of giving the game away against Australia after dominating possession.
Punivalu spoke with referees boss Paddy O'Brien after concerns around the breakdown at Las Vegas and says a repeat visit is on the cards.
"He's probably sick of seeing me frequently but you know I've got to ask the questions and that's how the picture becomes clearer when you ask a lot of questions and there's still some grey areas in the refereeing. But Paddy has been wonderful in helping us out but it's about getting better and moving on and be a better team next time."
After finishing second in their pool, Samoa will face England in the Cup quarter finals.
The other last eight clashes pit New Zealand against Canada, Australia against South Africa and Fiji versus Argentina.
