FNB Poor service

I have never been so disappointed did a credit card limit increase on Sunday 09/10/2022 .I received a confirmation that the application was successful and also received the pre-agreement. Then 3 days later I am only told that my application wont go through. After I spoke to 3 different consultants on the secure chat app/messenger. Only today I am told that My application will not go through. I requested to speak to the manager and Thandi Booi told me I cant speak to the manager. I will be called whenever the manager is available. Which can be anytime from now upto next year. I am so disappointed on FNB.
