Help-Pool Guy Is A No Show

[Dafreak]

I hired a company to open my pool. He came out the other day, pulled the plugs, shocked it and told me to fill the water up to the filters (half way). Did what he said but he was supposed to ocme back today and he didnt. Im not paying this little **** $400 to play games. All I need to do is turn the system on but being new to pools and this house I have no idea what to do. Should I attempt to do it or wait? I think all I need to do is prime the pump and flip the switch, no? The water is clear but there is a lot of sediment etc. that I would like to start filtering so that i can use the pool. Any suggestions?
