BroadStar Cable and Internet Scheduled an installation date and were a no show. Internet

I scheduled an appointment with Broadstar to have Internet put in my condo in the Villages of Bonita. I reconfirmed with them on the day of installation that they would still arrive between 1 pm and 5 pm and was assured the technician would be there. I had a family member who was on vacation spend the entire day at the condo and at 5pm I received a call that BroadStar had not shown up. I called the company and was told: there was no scheduled time, they tried to contact m at 2 pm and I didn't answer, I told her that was a lie (aren't cell phones great...they record all incing,outgoing and missed calls) and finally they  would try to contact the tech (Chris) to find out where he was and would call me back...you guessed it NO phone call. I waiited 45 minutes and called back...by now I'll admit I was hot. The next series of excuses were: there was no scheduled appointment...yet they admitted someone called me at 9am. They said that there was no tech scheduled for our complex for that day. I told her the last person I spoke to told me they called me at 2 pm I asked her if that showed on her screen. Her response was, "I can't give out that info." Why not???? You just gave me all the other info. her response was to reschedule (notice the word reschedule) my appointment or file a complaint and a supervisor would contact within 48 hours. My advise, RUN don't walk from this company. Their customer service is terrible. If it's this bad before the service is installed I can imagine what it will be like if there is problem later.
