Happy customer
Customer Service
We had a new alarm system installed by Bit4 in late 2016 after our old system failed. Luke responded rapidly to our need, taking an out of hours call and provided us clear and very helpful information on our choices for a new system. The installation went very smoothly. He and his team were attentive and courteous. Our first annual service was scheduled in and undertaken with minimum of fuss. We have had one issue of a failure light coming on (due to loss of phone network for the central monitoring) and this was dealt with quickly and efficiently when we reported it. Overall, I am very happy with the service received.
