Emailing is like communicating to an auto-reply wall.

Hi have settled my credit card with FNB, but another payment was made afterwards and my account is now in a credit. I need a refund and your email addresses do not seem to be manned by anyone as there is absolutely no reply and the call centre is useless, simply referring you to an email address if you have a request. I also need a paid-up letter asap before month-end. The service from FNB is atrocious. I need my paid-up letter and refund ASAP.
