Security not despatched

I received three calls today informing me that my alarm keeps going off. On the first call I indicated to the agent that I was at work and didn’t know what was going on. The second and third call I did the same but there was no one sent to check if things are still in order. I expected that on telling the agent I was not at home then someone will be dispatched to check what was going on but that is not what happened. If an alarm goes off am I expected to leave whatever I am busy with (in this case I was at work) and go check if everything is still okay at my place? Kindly furnish clarity on what service is provided with the package that I am registered on.
