Cancelled device but the premium is still taken fron bank account

First of all I do not understand why a trackibg company can not see when a car is involved in an accident and when the device is not active. I was involved in a car accident 13 March 2021 and my car was written off. End of March they deducted from my bank account. I wrote to Netstar informing them that I no longer own the car and would like a cancellation and I was advise the request would be done. Today my account is deducted again which I do not understand why. I want my money back because I informed you about the accident and received an email that my request would be done.WHY WOULD YOU DEBIT MY ACCOUNT?
