Bad experience with ABSA Bank

I recently received a limit increase on my absa credit card and ap**** online and was declined. When i phoned absa limit increase they said it was declined as affordability. I gave them proof that tgere is 2 accounts for vehicles that my sons are paying and does not come off my expenses.. After proof was e mailed i got no tesponse back from Tiffany Gould at that department after she said to me she will rectify it last week thursday 1/09/2022. Up to now no response. I have never slipped or paid a payment late and have enough money in my absa bank account. I will change my bank if this is how one gets treated at ABSA.
