Bad service- tracker was never activated

Installed my tracking device in December, had to get another technician to install the second device. Waited 4+ hours for the technician to arrive, after which I phoned numerous times to follow up after my scheduled appointment was missed. Premium went off, just to find out they never activated my tracker. Phoned again, they said they will contact me back and send a technician, never happened. Made another appointment yesterday for 8, followed up this morning to ask where the technician is, they said I’m in queue and no technician has been allocated. Company that doesn’t stick to their word.
