cant help with emergency only between 8am and 5pm

i phoned cartrack to find my vehicle location and they reffered me to technical and now i recieved a call from the service dept saying i have to pay for a new unit while no one can tell me whats wrong with my unit and if you want to log a complaint becuse my car could have been ****** because of their defective unit the tell me that its not an emergency they cant help me i must phone back at 8am tommorrow morning while ive been trying since the buisness hour of 12:15pm today so my car being at risk to be ****** is not an priority for them at all and according to them the unit is tottally useless if it breaks there is no way they can pic up that a unit is defective but they can recieve when batry power is disconected and when unit is being tampred with but not when the unit is ofline so then what is the use of having this unit if they canot monitor an online ofline signal even something as simple as whatsapp can monitor an online ofline signal and if the unit is defective they should have recieved a power failure signal but i was never notified. i spoke with mr nadeem at 17H58 he confirmed that my vechile safety isnt in cartracks concern saying also i must phone back at 8am tommorow
