Delayed response.

Today , 8 /8/2019 , my alarm was triggered at 9: 47. i received a call at work from ADT at 9:49, 2 minutes later. They informed me that my alarm was triggered. i asked them inspect. At 10:41 i was informed that they had just arrived at my house! almost an hour later!!. on my inquiry on the reason for the delay i was told that the area vehicle was busy!! they had to call the backup vehicle... ADT you must not play with my life , what would have happen if it was a real life emergency? The is the worst service i have ever received yet i am your client since 2009. I need to know what the delay was and why the backup vehicle arrived almost an hour later.?
