Stay clear - if they cant help on basic admin they cant help you in need

Pity I can't rate zero. Suffered extreme financial abuse, zero help and I am needing to prove my point. Due to their bad admin I send them a written notice to end my membership. They did not react. I had to go to my bank to stop their debit order. Then suddenly they can email and now I got letters that my membership is cancelled due to non-payment. I am very careful of my credit score and will not take such abuse and continuous mails and threats.

6 communications later I am still just trying to get a letter. "Thank you for voluntarily closing your account"
