No show for appointment!

I have been a Client with Chubb for over 10 years. A few weeks back (24th April or 1st May) I contacted Chubb to request a technician to visit to give my alarm a complete service. The appointment was made for 8.30am and I took the morning off to be at home. By 9.50am the technician hadn't arrived and there had been no contact from him or from Chubb's office. I called the office to enquire what was going on and they said they'd call me back. They did so at 10.05am to tell me the technician had had some 'issues' and would be at my house within 5 minutes. Needless to say by 10.25am(ALMOST 2 HOURS LATE) there was still no sign of him and so I left.<br> To date Chubb have never called to apologise for wasting my time or to reschedule another appointment.<br> I wonder if they treat a loyal customer of 10 years like this how do they treat new Clients. Interestingly Star Alarms have been in touch to get my business......
