Worst customer service

On the 20th of May 2022 I phoned Cartrack to inform them that my unit is not working properly as the app isn’t updating, it shows ignition off when the car is on and isn’t picking up that the car is moving. They tried to reboot it about three times where after they informed me that the scheduling department will phone me to set up an appointment to fix or replace my unit. On the 23rd i phone again to inform them that no-one has phoned as yet where they transferred me and i was told they will phone me for a booking. On the 3rd of June i phoned again and was told they will phone me, i also enquired about the debit order that didn’t go through but was told that it did. Today I received a sms that the debit order didn’t go through and i need to pay, which i did. But yet NO-ONE has phoned me to schedule an appointment to fix my faulty unit. On several occasions they tried to reboot but it didn’t work. So i am paying for NO SERVICE!!!! This is unacceptable.
