Bridge of promise & Compromised personal Account

I had several unauthorised debot orders and Absa promised to block these debits but they failed to do so, i am loosing R30.00 plus bedit order transaction fee every time i reverse these unauthorised debits; lately i get these unauthorised debit order twice a week, thats a lot of money i am loosing every month. I have been to different Absa branches but they promised to do something about these but they have failed to resolve this issue dismally. i want absa to reimbursed all my money i have lost (all transaction fees) this year. before i cancel my account with them.
