It does excellent work from top to bottom, starting with my salesperson, Bob Haff. I can reach him right away & he's so helpful. Other great folks there are Mark, the tech, Curtis, the owner, Jose, a manager, and office staff who always get back to me promptly.

Trying to use their internet billing services is time consuming, fustrating and fraught with errors. The system insists that I am already signed up for payments which I am not.

No resolution to date and a yearly bill that is nearly double the Briscoe bills of just a few years ago!!! Furthermore just heard a recording that any call off hours starts @ a $600.00 charge.
