Incompetence

I called the collections centre after I settled my personal loan and I was advised I overpaid by R358.77. I was then transferred to the personal loans Dept to refund the overpayment who said the can't help me and I was transferred back to the collections Dept who then transferred me back to the personal loans Dept and back again to collections. I asked to speak to a supervisor twice and instead I was just transferred to the previous dept. I will not tolerate such incompetence!!!
