Poor service

I do not see the use of the app if you can only dispute debit orders of r200 and less, I have been going inside the branch for the last 4 months to have the same amount of debit order disputed. When I call customer care I'm advised they can also just dispute the same amount as I can on the app, now my question is what about people like me who hardly has time to go to a branch to dispute your own money and on top of that you still deduct charges from that debit order, I don't see the use of the dispute debit order transaction on the app, with FNB bank you can dispute any amount on the app that you did not authorise, I have been with this bank for more than 10 years but I think I have to switch, the only day I had off was Sunday but the wholeday since opening time the branch was offline, now thats just to **** somebody off...
