TERRIBLE CUSTOMER SERVICE

I am extremely disappointed with FNB! I've literally begged the consultants to prioritize my application on Monday, and was advised that in the next 24-48 hours my query will be dealt with up till date nothing has been done. I've been calling everyday to follow up on my application yet no one can assist. When I called in shortly to follow up with the consultant, I was told that I did not call in on Monday, so did I just dream that FNB will help me in 24-48 hours? When I requested to speak to management I was told that I cannot as the team leader was on lunch, I DID NOT REQUEST TO SPEAK TO A TEAM LEADER. I was told that they cannot contact me when someone is available because they don't do out going calls. Should I continue to bank with a bank that does not take me serious? Makes me question am I banking with the correct bank.
