Take monies not due and *********** service!

Been trying to close this account for over a month. If you get any response from them, then its a copy and paste reply! Asked for the proof of payment, sent this to them over a month ago! To date still no account closure, no paid up letter but quick to keep adding interest and fees!! I want this account settled and closed and my paid up letter! I want all the charges reversed from the date i paid you!!! I can not believe this is how you treat your Clients? So unfair???!!! I am going to be laying a complaint with the Credit Ombud too as i have been pleading for weeks now while you just charge me monies not due to you!? How is this complying with TCF? And all my mails to your complaints department even get ignored?? Surely there should be a complaints procedure in place - i will be mentioning this too to the Ombud! I want this account closed and my paid up letter and all fees reversed as it is the RIGHT thing to do!!!
