My daughter is inconsiderate, manipulative, selfish, thoughtless, and is taking advantage of me, what do I do?

My daughter has been divorced for a couple of years. I have been taking care of her kids after school, and every other Sat. for a long time. I've been paying her car payment, and financially helping her. My grandkids are demanding, and difficult as times. I've found out that she stopped paying on a bill that I co-signed for and now its at the creditors at a time when I'm trying to refinance my house mortgage. She shows up late to pick up the kids, and never keeps her plans which throws me off my schedule. She lives like a pig, and I have told to get her **** together.She told me that she would help Thanksgiving morning and she calls up to tell me her friend is upset, so she dropped of one of my grandkid and went to console her friend. When my daughter showed up at 2:00, I told her to leave, my grandaughter, who my daughter picked up from her uncle's started to yell at me. I TOLD MY DAUGHTER THAT I DO NOT THINK WE CAN HAVE A GOOD THANKSGIVING TOGETHER SINCE I WAS UPSET WITH HER AND THEN SHE STARTED YELLING. SHE IS MY ONLY FAMILY, BESIDES MY HUSBAND, AND THEN MY DAUGHTER'S STARTED TO INSULT ME AGAIN, MY HUSBAND GO MAD AND THREATED TO MY GRANDAUGHTER, MY DAUGHTER THOUGHT HE ED HER, BUT HER DIDN'T, AND THEN MY GRANDAUGHTER THREATENED TO CALL THE COPS ON ME, AND I SAID GO AHEAD, THIS IS WHY YOU HAVE TO LEAVE. MY DAUGHTER IS DRIVING ME CRAZY. HELP I NEED SOME GOOD NONBIAS ADVICE.
