I cracked my screen today, now the screen won't work. HELP

My phone was dropped maybe twice within 2 minutes on a concrete floor. This wasn't even a bad crack. It was something I could live with. But after I noticed it was cracked, then I noticed it was not working. This is one of the best phones I've had (I had the iPhone 6 and traded it for this because it was so good). I really need help. I would need to know what I would need to do, replace it with a FoxPaw machine at the store or just buy a complete new phone.
