Credit Limit Increase

On the 11th of December I app**** for a credit limit increase when I spoke the consultant she said that I had been pre-approved for the increase and that It would take 5-10 working days for me to get a response from ABSA . Since then I have not heard anything and everytime I call the call centre I'm given another excuse. I spoke to another consultant Thokozane who said that he would get back to me before close of business on the 28th he said that my application was escalated and he would get back to me. On the 30th I called again and spoke to consultant Sad? and her reason for the delay was that ABSA had switched to a new system and my application was not processed as it was not captured on the new system. When I called this morning again the consultant I spoke to (Sholee) said that she would called back @ 8 to give me feedback . I am disappointed by the lack of service from ABSA and the excuses from their consultants
