Response of panic button after 1h!

I had some technicians from a company installing aircons in the house, after finishing the job they requested payment to be done, we realized that they stoled 12 meters of copper pipe, so we told them to return the pipe and the payment would be done. They refused to do that and threaten to undo all the job. I told them wait outside am going to drop my daughter for Islamic school and when am back we would resolve this. They refuse to leave the premises and blocked my driveway. So I pressed the panic button around 15h, expecting a quick response from ADT. Someone from the call centre called my husband Asking if there was a problem, so they could dispatched someone. Someone only pitch up around 4h10. By that time we resolved to pay the guys so they could leave our house ASAP, reason being, I was alone with my children and I didn't want them to try something.... This was very disappointing. The service we suppose to get from ADT is maximum 10 mins not one hour!! So much money we pay every month for what? Imagine if I was really being attacked. Not acceptable.
