Lack of feedback on credit limit increase

App**** for Credit Limit increase on my credit card on Friday. I got a call on Friday to say I need to send proof of income so they can finalize. I sent it immediately on Friday and I called this morning to check if they received the docs and I called Friday and nobody can tell me if they have received yet and when I can expect an outcome. I don't understand why the process is so long. Surely Terre should be a more streamlined process. All I hear is that my application is at credit. The specialists won't even go the extra mile to escalate it for me as it is very urgent.
