I am ready to take my business elsewhere

Please give me one reason I need to continue with your bank...this morning I thought I could increase my credit card limit and I tried the app, it was approved but decided to rather call in as I needed a bit more and when I app**** over the phone it was rejected without even a counter offer let alone a reason, then I went back to the app and the increase was approved immediately, what is going on here, I am sure other banks will welcome me with opened arms.
