Close cheque as you are unable to downgrade

I wanted to downgrade my cheque account to savings, I called fnb and I was told that I need to go to the branch, which I did and I expected them to downgrade the same day but I was told they also don't do it at the branch in bronkhorstspruit. They said they will do the application but I have to wait for about 7 days and check on my app. Until today almost a month my account is not downgraded. I had to pay as my account was on negative but nothing has happened. Now I no longer want the account as I am treated unfairly as is one of the reasons I left the bank. Please close the account as your client treatment has been the worst for the past 8 years with you.

Before my account was also premium and the charges were crazy. I called and they told me that I was charged per transaction with the monthly premium as well. The lady said it's because my account was opened as savings and was not updated. She said I had to be credited but that was not the case when I called again. I was ********** by the bank I trusted.
