First appointment, had to keep calling to find out when technicians would arrive. Then when they did arrive 1 hour before the time frame ended they said they didn't have time to do the job. So took off work for nothing. Called office and spoke to Service manager and rescheduled appointment for 2 weeks later and was assured our address would be first on the list for 8-12 and techs would be there about 8-8:30. 9 am came and still no techs or call. I called, they said tech didn't answer phone and they would send email and call back. Of course no one called back. So again I called at 10 and was told the techs wer picking up equipment and would be there at 11. Tech called at 11:15 and said they would be there in 30 minutes. Techs came at noon and left at 3 pm. The install was for 2 outside, 2 inside cameras and 11 contacts. No instructions on how to use cameras nor instructions on phone. Techs only answered questions if we asked. All cameras and contacts were working when they left. However, next day 1 outside camera offline and receive auto call that system has a communication error. Called Ackerman and had to do a test with them. They informed us that the office received the alarm and all was fine. Camera still offline and same panel error. NOT A HAPPY CUSTOMER!
