Poor service and Incompetence

My tracking device lost signal & it’s been 15 days no one picked that up, I called to set an appointment for repair, the appoint was for 08:00 today and it’s not 09:38 no one has communicated anything to me. I called customer service twice already and they can’t do anything about it, all they can do is “escalate”. I’m very disappointed and mad because it is an inconvenience, I set the earliest appointment for a reason. I now have to use a taxi or e-hailing service because I drive a high risk car and I can’t risk driving around with a tracking device that has no signal. The most frustrating part is that if I decide to cancel my subscription they are going to charge me for termination of service. I even call the technician who called in yesterday to confirm the appointment, he hangs up the call.
