Worst service ever given by a bank

If u could I would rate it - 100. It's been over 6 months dralin with an issue of my ewallet being blocked and FNB til today is still investigating and can't give me feedback even at the branch no assistance and when I call the customer care number it's either they hang up on me or just tell me they y will get back to me. I have money gaging with FNB and need to withdraw it
