Cancellation of membership & bad customer service

I've sent several e-mails since October 2018 in trying to cancel my membership with QVC (I do have paid-up points and just want to give it back to them) - with no success. Reasons for cancellation being 1) There is hardly ever place to stay; and 2) management fees becoming ridiculously unaffordable. Returned emails always said "Your query has been sent to the relevant department". Nobody ever came back to me. When phoning the consultant said Natasha is working with my file. However, Natasha is never available to take my calls. "She doesn't have an email or I cannot phone her directly or there is no manager I can talk to." While busy typing this review, Natasha phoned me. Only to be told I cannot give my points to someone if I don't pay my management fee arrear account. I disputed my debit order every month since I've asked QVC to cancel my membership. Now all of a sudden I need to pay a whole year's management fees (Sept 2018 to Sept 2019 although we are in May 2019) - this and other fees will now be included in a cancellation fee. This is ridiculous. I would never ever recommend QVC to anybody.
