LIMIT INCREASE

On Wednesday the 10th I received a text message from Nedbank saying I qualify for a credit limit increase on my credit card. The message said I should use the link in order to finalize and approve. I struggled with the link an instead called Nedbank. I was chanted from pillar to post but eventually got through to an agent who assisted me. She asked me all the security questions and then went on to do the app with me whereby she asked me about my income and expenses. I didn,t understand why all these questions because in my mind as soon as they say I qualified I understood that all checks and balances had been done already. Nevertheless I comp**** even though I was angry. I answered all the questions she asked me and in the end she said to me the amount quoted on the text message was actually lower meaning I qualify for more. She gave me the amount that I qualified for and advised me that she will refer the case to their credit dept who will finalize, she said I should get the response in 3 days time. Today I get a text saying the request has been declined. My questions to Nedbank are: I did not apply for this instead I was told that I qualified why are they playing around with our feelings and expectations? Why didn,t they do all their home work before hand instead of sending me a text like a puppy being tempted by a bone? I would have expected them to do their homework 1st before sending out messages. I need an answer, I feel this is so wrong and unprofessional, they treat us like dogs,

I am so so angry
