VERY VERY BAD AND DISGUSTING SERVICE

My account was in arrears and Nedban decided to double debit my account without my consent in February and i complained then they refunded my money howver the bank charges for unpaid debit orders were not paid. I was requested to make a repayment arrangement since i did not have enough money to settle my arrears. Arrangement was supposed to be for 3 months, March, April and May. Nedbank decided to double debit my account again on 22/05/2015 then my overdraft facility was affected again because my other accounts did not get money and my account was overdrawn again. I only picked it up when i received an sms from my bank stating that my account is overdrawn, i pulled the statement and saw the two debits from Nedbank. I was informed that i have to make another repayment arrangement since the one i made in March has expired. This is soo disgusting and stupid incompetency of Nedbank consultants cause now my name looks bad at my bank because of their stupidity. I have requested for my refund and they told me about 7 working days, i will not wait for that long cause i have to put my account in order now not in 7 days. I cannot wait to settle this loan and have a peace of mind...jerrrrr..
