Bad service continues....

And still I hear nothing from Nedbank...after I logged my complaint, someone phoned me back that same day. I was busy at that moment and said I can't talk right away, but anytime in the mornings I'm available. He said it's okay, I must check my email - and still nothing to this day....I am so frustrated now, after today I will have to go to my bank AGAIN, stand in line for hours AGAIN, just to get a stamped bankstatement AGAIN. I will have to go to the municipality AGAIN to get proof of residence and probably get all my other needed documentation certified AGAIN just to get out of Nedbank's system. I just want to cancel a policy, why can't anybody help me???? It's been over a month now...
