After reporting protectmyproperty for poor workmanship, slanderous accusations and deformation of character, they supply did nothing. Propectmyproperty a GOLD STANDARD certification from the NSI, downgraded my Grade 3 alarm to a Grade 2 system! Left me with a faulty system that voided my insurance! Reported this to the NSI who did nothing! If you would like to know more feel free to contact me. I have all relevant evidence!
