Standard Bank ******* debit orders

I closed my accounts with Standard bank 12 years ago when I opened a Bond with Nedbank. Since then I have moved to FNB for my banking. now, in 2021, I get a debit order and when I call the bank to query, they say I have not closed my bank 12 account. This was a process facilitated by Nedbank when I moved my debit orders and closed my accounts. So in 12 years I never received a single statement, or "new bank card" and now they tell me I need to go into the bank to close the account that has already been closed. This is blatant ***** and a Money Grab and bullying by big corporate
