poor custumer service

i wrote last week on the 24th December concerning FNB custumer care bad service. i was right about this bank. after my review they sent me message to inform me that they are investigating and i will be contacted shortly. i didnt get any resposnse. i contacted custumer service on the 28.29. and 30 December. i could not be assisted and no one could give me a straight. answer. this is not fair to me . i need the money to be reversed and i dont undrstand what is so difficult . it is like no one is willing to assist i am even thinking of moving and start banking with another bank..i am a loyal client but i hate the way i am being treated
