A broken spring means someone's car is trapped and they are already late. We Got The Call answers on the first ring, gets the details your tech needs, and books the visit.
Garage door calls are almost pure urgency: the door is stuck, the car is inside, and the caller has somewhere to be. They will ring three companies in five minutes and give the job to whoever picks up.
They are also calls where the right parts decide whether the job is done in one visit. A tech who arrives without the right spring or opener board loses the afternoon.
The questions your dispatcher would ask, in the order they would ask them.
