SUPERSONIC debit order years after cancelling contract

I used Supersonic in 2021 and stopped my account in that year. Now in 2024 a debit order automatically goes off my bank account for a large amount that is according to them outstanding. How can Supersonic just collect a large amount years after my service and contract has been stopped with them. I have emailed and phoned Supersonic to correct but no response from Supersonic side.
