Pathetic service - Insurance premiums not cancelled since Nov 2020

I sent an email to *** on 16/11/2020 to cancel my insurance - I used this email address because it was the only one I could find on the site and my calls were not being answered.

I eventually got through to the call centre on 26/02/2021 and they asked me to send the email to *** and to request my refunds via that email (2 premiums had since gone off)

I followed up on 08/03/2021 and 15/03/2021 and still no response. Another premium has gone off and another one is about to go off.

No one bothers to call you back or help you. No replies to any of my emails.
