Horrible Service

I opened an FNB Account on 21/08/2015 advising them that I am going through a divorce and changed my surname back to my ****en surname. Because I have no divorce decree yet I am so use to ppl telling me that they can't change my surname and FNB was no exception so I left it. They notified me a week later (05/09/2015) to pick up my personalized cards at the Branch and to bring the necessary for FICA. They even phone me during the month to ask when am I depositing money into the account. Come payday the 25th my account is FROZEN - call them and it's due to them NOT having my FICA documents - so halfheartedly I comply and send the documents again - where after I had to send the back of my new ID card and then my Marriage certificate - and when I started to throw my toys because they literally had more than a month to sort the documentation out they just threw the phone down in my ear! When I phoned back I just got transferred back to the person who threw the phone down in my ear. My account is now open but they can't give a logical explanation why they needed my Marital Certificate AND my surname is right according to them!!!!! FOUR WORDS - SINGLE MOM ONE INCOME.....
