personal loan miss-presentation

I app**** for a personal loan @Nedbank and first was pre approved with the interest rate of 9.25 then I went to the fourways branch and spoke to Kgomotso were she informed me they used incorrect interest rate and now suddenly its 32.65%....After a massive argument with Felicia at head office I decided to decrease my loan value from 60 000 to 40 000 Due to affordability...I then signed all the required documentation on Saturday the 14the of February,where I was informed the money will be in my account on Tuesday the 17th Feb....Then at 16:07 I received a sms stating I was declined...this **** poor work ethics and perfomance....Nedbank cleary lives of ill-representation as I was ill informed on four occations. I've also waited a total time of 7H30 min. At the Branch? And this was all for what exactly? Nedbank needs to patch-up on their personal loans department or they will be out of business soon.
