Best Bird Control Services in San Antonio TX

The one star I am giving is purely for the fact that when you speak with someone on the phone they are not rude and are pleasant enough. Technicians who come out are clean and polite...okay, maybe I should have given two stars. However, their service does not work...they walk around with a small regular aerosol can with a red straw on it and spray minimal points inside house...hence I have roaches running freely! Whatever they use it does not kill them.  I cancelled my service in July...over the phone we agreed that I would have one last service in August and that August payment would be last.  August ran away from me as I had major abdominal surgery to remove a cancerous node and when I called today (September 4th) to arrange for final service they said they could not help me ...that it was too late.  I said first of all your product doesn't work and secondly shouldn't they have called me to schedule? I never write reviews but this was not a good way to do business! Very disappointed.
