Slowing depleting credit on account, refusing to close the account

A few months ago I had a a credit on my account of about R400 - you have been depleting this slowly every month with "fees" - I have asked at least twice for the account to be closed, once which I have a confirmed receipt from Edgars. Take the credit and shove it : you already took the majority of the credit.

I will report this matter to the ombudsman should the account not be closed as per my requests.

I refuse to take any responsibility for payment on the account for "fees" once the credit is depleted.
