Bad service from Netstar and Auto& Gen consultants

I joined Auto & General in January 2019 and the package included Netstar tracker. On the 21st I contacted Netstar tracker to test the device in my car. I was told my warranty has expired and no one bothered to inform me but the premiums kept being deducted from my account for January and February 2022. I called Auto & Gen to cancel the contract with Netstar and I was advised that it was cancelled and I don't have any outstanding debits that I have to pay. I received an invoice from Netstar on the 02 March 2022 that I need to make payment directly with them but their tracker is no longer working in my car.
