Complaint of *********** clerk

On the 27 may 2019 I went to the branch in Saldanha to close my elite account. Signed the papers and I was advised to with draw the balance left in my account of which I transferred to my son's account. I am currently receiving smses that my account is in arrears and I must make payments. Arrears of a thousand and some hundred rands. When I called the customer line I was told that I must go to the branch I closed the account at. Am back in Durban and am told to go back to saldanha to rectify that. Who's fault is it that their clerk decided not to close the account? I refuse to pay those fees. Am told because debits have been returned unpaid since may that's why the fees are being charged on that account. I closed the account on the 27th of May. Anything after that I will not pay for. I refuse.
