Worst service ever

I thought the service from city of johannesburg and the eskom power cuts were bad but the service i got from nedbank was %$#@!(*&<br> I'm so disgusted about the service I got from Nedbank, on the 18 of August 2015 I app**** for a loan of R60,000.00 and it was pre-approved, I then submitted the documents on the 22/08/2015 at fourways branch and was assisted by Refilwe Ndimande however on the 26/08/2015 I was told that the requested loan amount was reviewed and the loan amount has been reduced to R30,000.00 and that was after I was calling to find out about the hold up, I then submitted other documents for the R30,000.00 and to my surprise this morning my account is credited with R10,000.00, how could I request for R10,000.00 and pay it for 48 months. I submitted the settlement letter for my other loan but still this is what I'm offered. I want this loan to be reversed because there's nowhere I signed for R10,000.00 I want someone to call to resolve this matter immediately. I'm even thinking of starting a blog and put it on the EFF website about Nedbank because you don't respect for you customers.
