Bad customer service

Where do I even start the service I'm getting for a brand I once bragged about when I joined them, This started when I opened an account for my son In January, both my account and my sons where blocked/frozen without letting me know that I need to take my fica documents to submits, fast forward to Feb same thing happened my account was frozen now my sons birth certificate was missing I;m not sure why do you hire *********** people but hey I guess that is how FNB does things now anyway, I sorted that out now today I woke up to a debit order notification for my person loan, I have 2 of them, Last year when changing my bank debit order date I sent through a letter saying that I get paid of the 28th From my company so that my debit order date can change which was done, lucky for FNB last month I got paid on the 25th, but still my debit order came off then I didn't mind because I had sufficient funds, Could I please get it changed back to the 28th because only 1 could go off as I didn't have sufficient funds when I called loans office to change it back to the 28th I'm told that my debit about will increase, I'm really ****ed off at the way FNB is handling your queries, I mean I'm I have wasted to much time with you guys going to your branches and calling you this is frustrating, I hope this is the last issue I have with FNB. Very disappointed client
