Negligent service

If you want good service stay away from this tracker company. I got their device installed in my car and app**** for a panic button also. It took them close to a year to deliver the panic button. My package had a terminal removal response, I removed my battery terminal 5 times different dates to test the service with no response. The only thing that works is their app on the phone. I have sent countless enquiries and complaints to no assistance. When I request a cancelation they want to penalize me for early termination of contract while they are the ones who violated the agreement.
