Bitter Thank You after 12 years

For the past two months standard bank has been ********ly debiting my account. I have reported to them and they refunded me and promised that it will not happen again. To my surprise they have debited my account AGAIN! For how long will I keep on taking my time and ask for refunds from them. They are inconveniencing me and I cant even enjoy my hard earned money anymore. When they refund me , they dont even consider the inconvenience I go through. All they do is just refund me and no compensation at all. I have been with Standard bank for over 12 years and this is the THANK YOU I get. I am very disappointed.
