Nedbank credit approval false

i have always been a loyal nedbank customer for the past 5 years not until i went to them for a further bond that is when i notised that i have been mislead by this bank.i noticed that i have been loyal for nothing i have stood by them through recession for what i should have left long time.i app**** for a further bond on my house then got the quotation,then got approval on the day that iwas about to sign with the lawyers i found out that the bank only approved R 920000 instead off the agreed amount of R 250 000. I took my time off from work thinking that i was gonna do real business with my bank as i have always gave to them but now its time for them to give back but it difficult..i would rather do a bond switch and go to standard bank were i will get more better service.Nedbank rate on my bond is now on 10.5% on and standardbank is 9.5% since the prime rate has gone up ,people don't trust these people.they will put you hopes high and drop u.I am really disappointed never though i would change my bank but in this regard were a bank does not cater to customer needs ...i would rather take my business else were...people be very careful....
