Unsatisfied fnb client

I am not at all satisfied with fnb springs service, I am on maternity leave and did not get payment yet and it is already time for me to get back to work, but any how FNB needed to change my surname to my married surname for me to get my uif money but still after three times I went in the bank to change nothing happen and still I did not get any uif, I need to pay rent my credit card is behind just because of fnb not doing their job and this is just to change a surname.
