VERY BAD EXPERIENCE

WHAT A MESS!!! I HAVE NOT BEEN TO INSIDE THE BANK SINCE 2019 BUT I NEVER THOUGHT THE EXPERIENCE SHOULD BE LIKE I HAD AT FNB COLLEGE LODGE. SO I HAVE BEEN TRYING TO CLOSE MY ACCOUNT BUT WAS INFORMED THAT IT IS IMPOSSIBLE BECAUSE A CELLPHONE CONTRACT IS LINKED TO THE ACCOUNT. THE CELLPHONE WAS EVENTUALLY MOVED TO A NEW ACCOUNT BUT FNB WAS CHARGING AND CHARGING ME ON THE OTHER ONE. MINUS R2400 TO BE EXACT. I PAID R1400 YESTERDAY AND TODAY I WENT INSIDE THE BANK TO SETTLE THE REST OF CHARGES OF R1009.50 AND FINALLY CLOSE THE ACCOUNT. I WAS TOLD I NOW HAVE TO PAY R1400 FOR THE ACCOUNT TO BE CLOSED. WHY...UMM BECAUSE I DONT KNOW WHAT THE OTHER R400 IS FOR I WAS TOLD BY KEFILWE MOJE WHO WAS ASSISTING ME, HOW CAN YOU NOT KNOW - JUST CLOSE THE ACCOUNT PLEASE. NOPE...YOU HAVE TO PAY THE ADDITIONAL R400 EVEN THOUGH I HAVE NO IDEA WHAT IS IT FOR. COME ON FNB JUST CLOSE THE DAMN ACCOUNT ALREADY. OR ARE YOU WAITING FOR THE NEW MONTH TO CHARGE ME AGAIN. WHEN I TRY TO CLOSE THE ACCOUNT VIA THE TELEPHONE I AM INFORMED TO GO INTO THE BANK. I DO THAT, I AM INFORMED TO CONTACT MY BANKER FAITH BOTHA. WHAT MUST I DO. ALL THIS TIME I AM BEING CHARGED ON EVERY TURN. PLEASE HELP IMMEDIATELY.
