No response to enquiry

I phoned twice to talk to someone about an alarm installation. Nobody took the time to ring me back on either occasion. Makes me wonder how reliable they would be if I did have a system installed by them????

FAB are back!

I had been a customer of FAB years ago and was always happy with their service. When they sold, we found that no company could meet my expectations.
Then I discovered that O'Brien Security Systems had been formed, set up by father and son team, Derek and Gareth O'Brien (Derek being the former owner of FAB).
I have been loyal customers of theirs since 2005 and am pleased with their dedication to customer service and attention to detail.
