Bad customer service - Account Upgrade and Overdraft

Last week Fri I went to FNB Bayside to upgrade my account and possibly take up an overdraft and the sales consultant advised me that I qualified for a bigger overdraft and I only took the amount I wanted. He further advised me that everything would be sorted out by the end of business on Fri or Monday at the very latest. Fast forward, it is now Tuesday and no feedback has been provided on the matter and the account has not been upgraded and overdraft not yet active on my account?

This is very poor customer service and if FNB cant assist me, I'll gladly consider my other options from other banks cause this is ridiculous!
