No response on credit card limit increase application

I app**** for a credit limit increase for my credit card on 2 January 2019 and was assisted by Nadia Fortuin via the call centre number. Due to our bond payment which reflects on my name at the credit bureau but it's actually paid by my husband, Nadia said I must send her proof thereof to her email address in order to rectify the affordability calculation for the limit increase. My husband wrote a letter to confirm that the bond goes off on his bank account and also provided his bank statement as proof. Both the bank statement and the letter I emailed to Nadia, just as she requested. I still haven't heard back from her and she said she'll confirm receipt and provide feedback regarding my application. Why must it be such a struggle just to get a credit limit increase? ABSA must also train their employees to have some customer service s****s! I need feedback on my application ASAP!!!!!
