Horrible customer service

6 months of trying to sort out a problem. I have contacted so many people and even provided pages and pages of proof that payments were made. Only to be told that I have only made half the payments and that the problem is my fault for using a reference number that I was told to use. Contacted people within FNB, the customer care, the complaints. Nothing gets done. I am astonished at the lack of care for customers and unprofessionalism within FNB head office. 1000% do not care about their customers.
