Poorest service provider ever. Braeking in on our premises without alarms going off.

Poorest service provider ever. They already broke in twice on our business premises at different times, without anything that get trigger on our alarm system at all. Our alarm system is running from a solar system that the system cannot go off. We did test it yesterday morning and it worked perfectly. Did not gone off at all. Still they got in and stole my inverter system and several other goods in my offices.

We have phoned ADT and want answers on how is it possible that from the access window where the burglars came in to the alarm box system in 2 eyes which did not go off at all? Technical Department cannot even tell me how is it possible but this is there systems?
