VERY DISAPPOINTED WITH PROCEDURES ON LOANS!!!!

I am so very disappointed with my Bank. I think it is totally unacceptable that a system can APPROVE a loan and then the "back office" DECLINE it!! To play with peoples emotions is a disgrace, I think you need to work on something that goes hand in hand with the system and the "back office". I actually was only looking for a loan for literally 2 months as I am receiving a substantial sum of money mid- to end January 2019 (which I gave the Sales person at the Bank proof of). I already have an existing loan so just wanted to add to it and would have been happy to have it flagged that when the money went into my cheque account (where it is being paid) they could have taken it off. I have an excellent credit record (as I check my TransUnion Report) and have never defaulted with any of my payments ever. Due to unforeseen circumstances I just required a little help for Nov and Dec. So future customers beware, all goes well in the "front office" and at the "back office" everything turns sour! I am a rather distraught client right now and am nervous when I need to invest with Nedbank.
