Tracker keeps on taking money off my account even though I sold my car months ago

I have been trying to cancel my subscription for the last 2 months and now that we are in the lockdown, there is no way of reaching tracker. I sent 11 emails, 7 cancellation requests on their site and many phone calls, nothing... they are still debiting money from my account while I sold the car months ago.

I don't think this is legal to be honest, this company is some sort of debit ***** company, they just keep of taking money without legal framework.
