Poor services

I have been a happy client at Nedbank till recently. I have been to 3 branches to apply for a Credit Card increase and I've been sent from pillar to post with conflicting information. I was told to call and I did...i could not get help. Called to find out if Springs mall branch will be opened on Saturday and I was told I would be opened and I went there, it was closed! Went there again on Sunday, spoke to the lady in the front desk...she took my ID and Bank statement because they can't help me,I must call the Credit card department. She scaned my ID and Bank statement and sent it and No one called. I called to follow and the lady I spoke to....sounded bored and told me it declined. Well the line was bad and she struggled to hear what I was saying as I was struggling to hear her too. Can someone please call me and give me proper services that I know the bank off please. This is not what I would expect from Nedbank. ***.
