Poor Call Centre Personal Loans service

i have made a call to Nedbank personal loans on Monday or Tuesday... to make payment arrangement..the first operator, drop the call in my ears, the second operator told me that i have to call MDS, and i kept asking her questions until she told me to call Mds and droppped a call in my ears, i call the 3rd time the lady gave me the number and told me to call MDS...you see the reason we go to branches is because firstly we have accounts with them(Nedbank), then we are told to call some unknown company, and we dont have funds to call such companies that we dont know. when i walk into a branch i know i will be making a free call. at the moment im unemployed and would like to make payment arrangements thats all. please sort out the rudeness from your Call Centre agents... Thank you
