Vehicle write off but still claiming subs

The vehicle was written off on the 31st of May 2022. Tracker were notified and had to provide the trip log. Tracker is still deducting premiums despite being notified by the driver that the vehicle is no more and is a write off. Why are they not cancelling the direct debit and refunding the July subscription. Take for May and June as the notice period but please enough is enough as though not havuing a vehicle is bad enough but to continue squeezing payment out of a stone is not really the done thing.
