Bad customer service

I booked an appointment for Saturday the 14th and the technician called to say he is running late 4 hours later he calls to tell me he is not going to make it we should reschedule.

Today again same thing happens, our appointment was at 10am,he calls me at exactly 10 to tell me that he is running late again. I then called customer care center they actually told me that I can cancel my installation if I wanted to. That is the kind of service we get as much as you try to be patient your patience gets thrown right back into your face.
