I lost 2400 points and support don't reply me!

I bought 3 packets of 100 loteries tickets point for each click and two did not work. I lost 2400 points and support don't reply me.
When I click I don't receive the bonus of 100 "lotery ticket bonus"
Are those packets stackable? I thought that bonuses were not stackable, eg you can have only one active at a time.
