Contractor late

Lauren • 28. Married 1/17/14. Had our first baby 1/14/16! Second due July 2017
We hired a company to lay down laminate in our house. It's going to be $3,000. They were supposed to come at 8am this morning and it is now 9:30 and they still arnt here. I didn't recieve any phone calls from them saying they'd be late. I'm so upset! Paying someone this much money and they are so unprofessional. I almost want to call it all off or something. 
What would you do!
