5 weeks and still no response

On 30 September 2015 i called for a credit limit increase on my Absa Platinum credit card. I was asked to email my latest payslip, which i did immediately. I then received an email (obviously automated) requesting 3 months bank statement. I then called to advise that i only bank with Absa and have no other accounts elsewhere. The consultant advised that if my salary is being deposited into my Absa cheque account then there is no need for me to submit the statements as they can access it from their system. Since then, i have made 4 follow ups and i they are still not able to give me a response to the increase request. They keep saying i have to wait. I have been waiting since 30 September!!!! Every consultant i speak to says they have moved to a new syatem and its caused a backlog and they are unable to say how much longer i have to wait. I have been a client of Absa for over 20 years and credit limit increase took 24hrs in the pass. How can they claim to try to improve their systems when the clients are having to now suffer the consequences thereof. This is UNACCEPTABLE!!!!
