I'm not usually a complainer, but I have to!

I have Dish Network, and one of the company's technitions was supposed to be here last Friday to upgrade me to HDTV.  I took the morning off of work to be home when he arrived.  He called and said his van broke down, and he would not be able to make it that day.  The next day, Saturday, he called and said he could be at my house by noon.  I waited until 2:15, and he had not arrived.  I had to leave for another commitment, so I did not get the upgrade done.  The technition has not called, and has not come to my home yet, and it is now Monday.  I called the Dish Network office this morning, and after 30 minutes of trying to talk to a "real" person, I now have an appointment for this Thursday, sometime between noon and five p.m.  I wonder if he will show up for this appointment or not.  I guess we will find out on Thursday!  I just dislike taking time off work to wait for someone who never shows up, and never bothers to call!
