Pissed off at a cable company

Got disappointed with a cable company's failure to install.

1) Why didn't they just tell they can't install on the schedule d time.
2) Overpromises but underdelivered
3) Full of air (puro hangin)

I couldn't believe that such a prestigious company would be treating a public servant like me and that would waste much of our (family's) precious time.  If you couldn't do the installation just say "NO."  Please don't give false hopes.
