Credit card limit increase

I'm so disturbed by the lady that assisted me when i called I to increase my credit cardlimit I gave all details and just like that she advised me to go I to the branch my proof of address and my id I've been a customer with standard bank for so long that you have no way of assisting your customers properly. Yes I get it CPA needs to be checked but on first attempt and I guess maybe one thing I confirmed she wasn't happy with and decided it's a no and I need to go to a branch. Without even asking other question. Like i don't work and I have all the time in the world to just jump into a branch. I surly feel that I can close all my accounts with Standard bank after this. You clearly don't care about your customers at all ?????????
