Any advice on how to sent and receive heal kits from Facebook friends

After I've updated my game I didn't get any more healkits from my friends on Facebook ....I've re installed my game and uninstall Facebook and download it again. ...nothing seems to be working I have over 129 friends. ...
It sounds to me like the friends you're requesting from donot play this game therefore you aren't receiving any because the invite is being ignored one way to check it would be to ask them personally do they play rugby manager on facebook if not then there is your answer if so they have either turned off their facebook gaming notifications or they've hit the cancel on you when your requesting
Add people from the Rugby Manager Heal Kit Circuit facebook group as friends.
