There was no pre-contact from your representative. Don't know if he came to the house. Didn't knock on the door to let us know he was here so we could unlock the screen doors to the patio. Don't know if he actually serviced the tubes two places in the house. Also notice the representative was not Braxton. Where is Braxton, one of the best you've had over the 17 years we have used your service. Can you prove the representative was at my house and what services he performed. I can't! Thanks for your time.
