Can't get pass level 65. No power ups given during game, unsure how to even earn power ups. Any suggestions? I'm ready to stop playing the game. Not great.

I have zero Power-Ups after initially getting about 3 or 4 of each. It's been over 20 levels, and I haven't received any one of them. Is there a place to buy them or something? I am on Level 48, and I can tell this one is going to be near impossible to even beat at all with 0 Power-Ups. I one starred 46 and 47 after 3 starring every one before that. It's just not possible to make that many matches for what is required....
