Limit Increase on my Credit Card

I am a loyal ABSA Customer i had financial challenges in the past two months and my debit order were not going through accordingly. I managed to settle all my outstanding debit orders end of November and my account is almost up to date. I requested a limit increase on my credit Card but is declined. I have send proofs of my payslips showing that i can afford to repay the credit card the problem started when i changed jobs month end of August where by my previous employer didn't pay me my salary in full. What must i do as a loyal Customer who is always paying his credit card using debit order. My ID number is ********** 609084. Why are you declining my limit increase while you are always getting a payment for the credit card every month. Have i ever not pay my credit card? There is no fairness i am only good on paying interest but i am not good to be given limit increase?
