Terrible Service from Cartrack

We joined Cartrack in February 2024. From day one, the service has been shocking. The tracker that was installed in our car drained our battery, to the point where it wasn't rechargeable. We had two other technicians come out to inspect it, and the last technician advised we buy a new battery and Cartrack will refund us. He had given us the invoicing details, as well as who to send the invoice to once done. It has been 4 months of waiting for this refund and we haven't received anything back. I have emailed MULTIPLE times, and phoned in almost every day to follow up - and all I have been told for the past 4 months is that "your query has been escalated" and no one has the decency to get back to me, letting me know what's been going on, and so the process continues. The communication from Cartrack has been shockingly disappointing, and I would definitely not recommend them to anyone.
