Credit limit increase takes forever

I have app**** for a credit limit increase on the 18th of November. It is promised that it will take 3-5 business days to process. It's now a month later and there's still no action. I called the complaints department numerous times and they have assured me that they have made it priority but it's been weeks since that as well so it's a lie. I was told that my scores mismatch and it's supposed to be higher and it gets outsourced to a 3rd party company to handle. But a MONTH??? Come on Standard Bank. I banked with you guys since I graduated. Everyone tells me to move to FNB but I get too lazy. Maybe it's time to move.
