Misinformed and now they will not correct

I decided to change banks to nedbank thinking i would get better service but am starting to regret my decision.<br> <br> When letting the personal loans department know i have changed bank accounts i was told to make a cash payment for my loan Ref *** i then made the cash payment and then they also debited my account making which means two payments was taken off.<br> <br> I then had to spend my Saturday morning at the bank trying to sort this out after being promised this would be sorted out within 24hrs, its now the 3 February and no money was paid back into my account after being promised and manager would call me to sort this out call reference *** i feel this is a both unprofessional and a complete let down as its the first month with this new bank.
