Coin Master complaint: Spins from inviting friends

So I have invited multiple friends to join this coin master game and majority say that it doesn’t work, they download the game and try to be friends with me but it doesn’t allow us to be friends. Now for the three people that it did work for it did not give me the 60 free spins. I investigated that it said it wouldn’t work for people that have downloaded the game to their phones before but that is false. My boyfriend had the game before but it gave me the free spins when I invited him and the three other people (that the game successfully added as my friend) it did NOT give me the free spins! I am getting sick and tired of getting so close to receiving a reward from a challenge or competition I just need a few more spins and “oh I’ll add one of my friends to get free spins” but then it doesn’t give it to me and I miss the reward. I am this close to uninstalling the game and telling my friends to uninstall it
