Chubb was a good company but National sucks!!!

In the last week my alarm went off a few times without National ever phoning me. Today I tested the alarm, again they didn't call...so I phoned them. First 3 attempts they did not answer my call. 4th time somebody answer and when I ask why they didn't phone he said my alarm didn't go off. I asked what can be wrong just to have him cut me off. So National I think its time for me to cut you of as well.... Why do I have an alarm if its not working..... At least refer the client to the technical team to fix the alarm.... Chubb was a good company but National sucks!!! New owners need a wakeup call - service worse ever!!!!
