Account closure

I need to know what can I do for edgars to close the account I had with them. In February 2021 I asked for settlement amount I payed and asked them to close the account immediately and for two weeks I was going to the store to check if the account was close after that I was told not to call anymore the account will be closed in 14 days. November 2021 I received emailed statement with a balance ***ing) and its been increasing ever since. I am not interested in knowing who has been using the account all I want is for them to remove the debt and remove my name on their system I don't have any business with them. Edgars service is pathetic
