Accounts department incompetence

After receiving messages that no payment was made in my account even though I knew I had made a payment, I phoned Standard Bank only then was I told it was in arrears. I had asked for my monthly statement to be sent to via email- I have never received even a single one TO DATE, hence I did not even realise that my account was in arrears. I made arrangements with Linda to pay off the arrears and gave my account number to be debited on the last date of the month. After she supposedly updated, she then told me that the bank will phone me monthly until the arrears are paid off. I received the call in May which was a machine operated call which gave me a number to call Standard Bank to make arrangements- AGAIN? I kept getting messages about unpaid account until I sent a complaint to their Customer Relations and they responded on the 19th May and said they have updated- I thought finally I would not get ANY UNSAVORY messages- I was wrong- the messages kept coming. The debit order for May went through on the 31st May, this morning, 1st June the first message I get is from Standard Bank- ABOUT A PAYMENT NOT RECEIVED AND THAT I MUST CALL FOR PAYMENT OPTIONS- REALLY? SHEER INCOMPETENCE!
