Cannot Cancel my BEAME subscription since July last year

I sold my car in July 2021 and immediately tried to cancel my BEAME subscription by phone. This was unsuccessful after multiple calls. I tried to call a number of time's and then reverted to emailing them. I have emailed their cancellations department 3 times since JULY last year and still they keep either trying to debit my account with the monthly fee or send me messages continually to pay the outstanding amount since the end of July on a more than regular basis. This is absolutely ridiculous and one CANNOT get them to cancel this subscription. Calls, mails just seem to be ignored. I have continued to pay additional payments beyond July to keep them happy but have had enough. I see I am not the only person who seems to be struggling to cancel their subscription. Enough already. Is there Nobody doing any work or is someone to lazy to get off their backside to actually just stop the premium. Why must one fight with companies like this to stop payments for months on end.
