Poor customer service, despite (false) promises!

I have had a Cartrack device fitted to my vehicle for more than 7 years now. For many years the device was operating 100% and the service good. However, everything changed after a battery replacement in July 2020. The device started registering false panic event alerts to the system. After some months, I requested for the device to be replaced, as I thought that the problems were due to the age of the device. The device was replaced a week ago, but the false panic event alerts just resumed that same afternoon, despite the device being replaced. All my efforts to try and further address the problem have just resulted in messages not being responded to, despite automated e-mails thank me for my email, acknowledging that Cartrack received my enquiry and a note that " We strive to achieve an email turnaround time of one working day." The e-mails then continue that "In the event you require urgent assistance, please call us on *** during 8am and 6pm on Monday to Friday, or from 8am to 1pm on Saturdays for assistance from one of our dedicated agents.", which also proved to be a false promise, as I have been holding the line listening to falso Cartrack adverti*****ts for nearly an hour now, without any success. Is this the effective age fourth industrial revulotion???
