Not closing accounts and charging admin fees

I had a revolving credit account for many years with you. 2-3 months ago I called for a settlement value after numerous sms's from Standard Bank offering me a discount. I did not receive any discount. You were also supposed to close the account, and don't tell me now I must contact a different department. The settlement was for under R100 and the mutual understanding for almost 3 years was that the account be closed after settlement. Now I see, a few months later, that my account was not closed, and that it now stands at approx R69 again. I did not agree to a lifetime monthly service fee and these fees are just *******. In addition, if you have to review my account, you will see that during 2018, my account went into arrears and a payment plan was made. If taking the induplum(excuse my spelling) rule into account, you actually owe me money. I did not pursue this earlier as I just wanted the account closed without hassles. You have now created hassles after I kept my side of the arrangement. My expectations are that this account be closed IMMEDIATELY, and my account be reviewed for any credits I am due. After this complaint, I will be approaching the ombudsman for your ********* way of doing business
