Unable to close Edgards account

During October 2020 I decided to close my Edgars account. I paid the full outstanding amount on 30 October 2020 and send an email to close the account. I first tried reaching them by phone, but that seemed impossible as the lines were constantly busy or cut off. I then received a statement with Club fees payable by end November. I started phoning around and eventually had to speak to Edgars, Edgars Club, Edgars Accounts department and Edgars collections department. I also had to resend the email to all of those departments in order to close the account. I refuse to pay the club fees because I closed the account and I didn't use any Club benefits. This account still hasn't been closed and I am now even being billed for collection letters!
