Frustrated with app crashing and nobody able to assist to finalize limit increase telephonically, immediately!

Feeling frustrated. Tried to do something simple (as I have a few times before) and that was to increase my Revolving Credit Facility, however the app got stuck and wouldn't move forward. I then closed the app and went back in, but with no option to increase as the previous 'application' to increase is now stuck in a 'pending' state. I wasted about 40 minutes in total on Tuesday and again yesterday to attempt to get through to someone to assist. Finally, after I got through the lady said she is going to escalate it and now I wait. It's now been 2 days and I needed the funds 2 days already. What's the point? Defeats the purpose of having the option to increase immediately and then you wait......
