Extreme disgust at companies internal matters negatively affecting customers.

Paid up my account 2nd week in November 2020 and requested a paid up letter via email. Visited the Canal Walk branch in December to only find out my account have not been closed. a very helpful assistant then closed it on the system and requested a paid up letter and to date together with weekly emails requesting this I have still to receive the letter. This paid up letter is needed to remove a Debt Review indicator from the credit bureau and its been 4 very frustrating months. Calling the RCS call centre is a complete waste of time as I am yet to speak to a person.
