Pillar to post

Hi i'm a not so happy client of Nedbank i called in to try and make arrangements to pay off my credit card account to my surprise it seemed like the consultants were not sure what to do they sent me from pillar to post to no success and next thing i know they will be busy sending me letters that i haven't paid them i left about 3 voice messages as holding on the line was eating my airtime and i finally got an answering machine asking me to leave a message which i did but till today i haven't got any feedback or call back i really don't see the use of leaving a message for them to call you back if they never do and all i need is just to clear my name somebody please Help me !!!:(
