Disgusting poor service

I took out a contract with Cartrack for a tracking device and services in November 2022. Since the device has been installed for over a year and 9 months, I haven't been getting the services I have been paying for. The device is faulty since installation namely brief below : *The location of my car and what I see on the app is two different locations. *I can't switch on car watch on the app as it I keep getting an error that I need to switch off my ignition while it's off already. * ignition on the app shows that it's on while am indoors with the keys of the car and it's off since the device was installed. *The car direction on the app would show the car facing east but the device shows the car is facing west. I have been paying Cartrack for services for more that 1year and 9 months which the services are not being offered by Cartrack, but miss a payment you will get thousands of calls telling you about your account being in arrears, when you explain to them that the services am paying for am not getting. The accounts department just tells me to pay my account to avoid being handed over to the lawyers. They don't even have empathy to Escalate it to the relevant department for assistance. I left things hanging because I didn't get any joy and avoided my name to be on bad records due to payments. Months went down the line and still seeing that nothing is happening from Cartrack. I sent several emails to their service desk which is *** not automated response or feedback is provided on that email address. It's 19 days later today with no feedback or response from Cartrack on what's the way forward about my complaint. I am requesting that Cartrack can refund me the monthly installments charged from November 2024 till today for the services I didn't get from them and their device that hasn't been working since activation. I also want to cancel my services with them without any penalties as they are *********** and lack customer service. I regret the day I took the contract with Cartrack!!! Thank you
