Zero3 communications have been everything they promised, from beginning to end. Alicia helped set up the new phone system at our school and was very helpful, accomodating and always available. Sarah assisted with a separate installation of motorised gate sims. Sarah was super helpful, friendly and prompt in her actioning. Zero3 understand our needs as a school and can accomodate almost any request. I highly recommend them as they are easy to work with, highly knowledgeable, efficient and effective.
