First National Bank...Just red tape

I am really disappointed with the level of service we have received from First National Bank, Credit card limit increase division. Earlier this week, we requested a limit increase, which was approved, all the documents were submitted and we were advised it would take 8 hours to reflect. When nothing happened, we called back, and were then advised that it could take up to 48 hours to reflect. The amount of red tape and almost robotic like staff, who all seem to have no ability to assist, make it seem like an impossible task to have the most basic banking completed. Emails are not responded to, and when I state that an email they said they have sent has not been received on my side, they do not resend it. When we were in the bank to find out what is going on, the staff looked powerless, to assist. This started on Monday this week, it is now Friday, and still the limit increase is still not reflecting. We have been told that it has been escalated, 2 days ago, yet still nothing.
