Not in arrears,but calling,sms & charging me 4 it

I am so angry right now. I have tried my best to get my nedbank CREDIT card up to date and have been paying for the last couple of month without fail. Even have a stop order on my account to make sure I pay my account each and every month. <br> <br> But I have their legal department sending me sms's and calling me every month about making payments on my account. I called them this morning to ask what is going on and they told me that I was given over to the legal department ( which I totally understand). My problem is if they going to call me every month and charge me for every call and debits the credit I pay every month, than I will never reach the goal of paying off this account.<br> <br> I called the call centre today and spoke to over 8 people and at one point one of the agents dropped the call in my ear. ALL I WANT FROM NEDBANK IS TO STOP CALLING ME AND STOP CHARGING ME FOR THE CALLS OR ELSE I WILL NEVER GET TO PAY OFF MY ACCOUNT. WHAT MAKES ME EVEN MORE ANGRY IS THE FACT THAT NON OF THE AGENTS COULD HELP ME WITH THIS.<br> <br> Ii AGREED ON A MONTHLY AMOUNT. I AM NOT BEHIND WITH MY ACCOUNT AND I WOULD LIKE THEM TO STOP CALLING ME. ITS VERY SIMPLE.
