Using service vehicles to party and disrupt our sleep

I'm not a client but would like to complain about ADT's staff..not sure if they were off duty but they became part of a problem that we have been battling with for a few months now in Mount Croix/ North End Gqaberha (2 vehicles were parked opposite my house: Service numbers: 47925 and 47610) making a noise at 4:48am in the morning they seem to know the neighbors and when my husband approached them about distrusting our sleep, the one staff member or driver told my husband to call their company..the audacity!
