Unauthorized Debit order

I am really not happy with these guys - after trying to update our will for over two years without proper assistance we went elsewhere. However we had two policies with these guys to "cover" our estate fees should something happen to us. I cancelled both our policies on 7 NOvember 2021 only to be told November cannot serve as my notice month as i have to give a full calendars month notice. So my notice month would be December even though i no longer wanted the service nor could i afford it. Senior management was included in the email as well as had numerous telephonic discussions as they then tried to retain my business.

1Jan 2022 came and the debit order went off yet again - it was then immediately reversed. 1 Feb 2022 came and guess what the debit order went off yet again! After throwing my toys with the same management copied on the original cancelation - it was found the one policy was never cancelled end of last year and the employee who did it left the companies employment. So they wanted to cancel it now at the end of Feb. I however refused and insisted that my debit order is refunded immediately as i have already gone elsewhere and have not been making use of their service since December last year.

It is 17 days in since i started querying this matter and still no one has bothered to make contact or refund the debit order that was cancelled and yet again taken off without my consent.
