No feedback or response after numerous calls

Several weeks ago I app**** online to have my credit card limit increased. I completed the process and I was provisionally approved and the system said it would take 2 to 3 days. A week later after no response I phoned the call centre (escalation dept) and spoke to Tugdeline who said there was no record of my application but she would forward a mail to the limit dept. A week later still I had received no feedback so I called again and spoke to someone who said I should submit all my information and re-apply with her over the phone which I did. Days later and still no feedback or any response. On Wednesday I called again and spoke to Linda Masimolo who said she saw an escalation logged for me and then asked if I was asked to submit documentation even though I was told by the previous person that I would not need to submit anything as I am a Absa client? She said that I would be contacted or reveive a sms that same day which now is 3 days ago again. What do I need to do to receive assistance a reply feedback from Absa? I have been a customer with Absa for 9 year and have never missed a payment. I this how you look after your customers?
