Cancellation not happening

I sent various emails to cancel my service as I have sold the bike months ago. They keep billing me but do not supply cancellation figures. Now they state that they cannot cancel, I first have to settle the last billed amount. This is ridiculous in 2024 and so backward. Just provide the total figure to get you out of my life and stop harassing me with your childish approach to business, how difficult can it be. Legally i have cancelled your service with notice to the mail address you supp****, NOW process my instruction.
