PLEASE CLOSE MY ACCOUNT

I've been trying to close my Nedbank account for the past month now. Each time I go on their app I'm given excuse after excuse and each time I go online I'm required to start the request form scratch. WHY WOULD THEY NOT KEEP A TRAIL OF MY COMMUNICATION? After countless times of contacting them online I was finally told to call their call centre or go to branch. I complained on the app and someone called me, I asked them to call me after an hour and NO ONE CALLED ME BACK! WHY HAVE AN ONLINE SERVICE IF I MUST STILL CALL A CALL CENTRE? OBVIOUSLY I WORK, WHERE WILL I FIND TIME TO GO TO BRANCH? IN FACT I DON'T WANT TO GO QUEUE AT A BRANCH EVEN IF I HAD THE TIME! Now the account keeps accumulating fees which is what is was avoiding when I requested to cancel after the last billing date. Now who must pay for the current fees? Next thing this will be listed on my credit profile. I AM FRUSTRATED BY THIS GREEN BANK!
