No customer service or people s****s

We contacted Alpha security to install panic buttons on an existing contract and alarm system as well as an assessment on the system. It took them three days to send the correct order on which we had to pay in advance. We were contacted to make an appointment. An technician were sent out to do the installation. He informed us that he could not do the installation as it has to go through the computer server (which is not correct as per our it contractor). He promised to be back by the Thursday when the IT contractor is available. This was reported to his office as well as on the report given to us. The office in spite of knowing this did not schedule an appointment. When I inquire when will the technician will be on the premises I was informed that I should have scheduled an appointment (she admitted that she do know that he was supposed to be on site.)
