Credit limit increase

I received a call from Absa advising that I qualify for a limit increase on my gold credit card. A few days later I get a sms advising that my request for a limit increase has been approved. I then contacted absa to confirm and they advised that OM their system it shows up as declined and that they will investigate why I received an incorrect sms. Today I receive another sms from absa advising that they are awaiting my payslips in order to finalise my credit increase request. I contact absa again and again they say they going to investigate. Yet, no one from absa is contacting me to let me know. I want to know what is going on asap
