Bad Service

Hi FNB for the third time. This is the third week now and I still haven't received help. I am really frustrated. Can someone at FNB please please please assist me. I have never in my life experienced such bad service anywhere else. I have been trying to resolve this using my banking app and calling the contact centre but no one can assist me. I wont be able to pay another month on an account I am not using. Please I am begging you to help me close this account
