Poor client service from absa credit card. Uncaring attiude

I am deeply disappointed and dissatisfied with the way absa credit card delays with my limit increase application.i am an absa credit card holder for almost 10 years with an impeccable payment record.last week an agent cled me offering a limit increase on my card account been musi mohasi and we went through the whole application process.he asked me what amount I would like max been R60 00p and I advised that I needed a lower amount.i then called yesterday and was told it was declined.my question is why then am I not offered a lower credit limit increase amount seeing that I am a client of good standing and why are we approached for a limit increase just to be declined.very poor client experience
