First (worst) National Bank is angry that I don't want to bank with them anymore.

I requested the account to be closed at the La Lucia branch 5 months ago. It was supposed to take a month so I allowed my salary to be deposited into the account so I can cover any charges that might accrue and to allow time for my debit orders to be switched to my new bank. Now, ( as of the 2nd of November 2019) Im getting threatening SMS's about this account that is supposed to be closed that it is overdrawn. I spoke to a private banker last week and they were of no help ( as usual) but I accepted the situation and asked that a note be made that I would make the payment on the 25th of November 2019 and then close the account. Their automated calls are not helpful too, either to myself nor to the bank as i dont get to make an arrangement. The money owed is also not consistent, the private banker told me I owe R-359 (which I still have the conversation) and according to their SMS's i owe R602.51. It is no consequence to me how much I owe, i just want that bank out of my life. I will make payment on the 25th of November 2019 as I do not have the funds to make the payment at this time. I work as a digital marketer and i noticed that you cant mention nor tag them on a social post. i am sure they have locked it and I will be inquiring with FB and the other social media's companies to find out if this is allowed (I'm sure its not).
