ABSA Notify Me - I can create a notify me message, but I cannot delete it!

I accidently signed up online for ABSA Notify Me. Now I get emails for three accounts on a weekly basis and have to pay for every email. I tried to cancel it on the website, but it does not allow me to cancel it. I can create a notify message, but I cannot delete it! The emails I get, display "For assistance please call ***", but when I phoned this number, I get a message: "this number does not exist!" I phoned ABSA Support, and the consultant said, He cannot stop it and I have to go to a branch to stop it. I then went to the Westville, Pinetown branch where there was a long queue of people waiting. After 30 minutes the queue did not move, and I gave up. It seems like ABSA is deliberately making it as difficult as possible for you to stop a recurring expense!
