Been waiting for a technician for over 7 weeks now

I've been getting a call from Cartrack every time I switch off my car since 29 October, they receive a power event alert, my device could be faulty and they keep saying they will send a technician to assess and repair. Its been over 7 weeks now and I'm still waiting. I've reached out via WhatsApp, and calls and every time I'm told the repair request was logged and someone from scheduling will be in touch to arrange for repair but no one called me. I am tired of explaining the same thing every day, please cancel my contract.
