ACCOUNT CLOSED, BUT STILL GETTING INVOICES

I closed my ABSA account a month ago, but I still get emails with statements for the account fee. I sent ABSA a direct message on twitter communicating this to them, but simply got a reply that I must go into the bank to make the necessary changes. I'm sorry , but I've done this already and closed all my accounts at ABSA, for this very reason. Please sort this out and contact me, I'm not going to any of your branches. Get it right.
