Very unfair without my consent

I'm not receiving my notify me smses anymore. I called the customer care help line. They told me that the notifications are sent to my App. My App is not open 24/7. So, how would I know money has left my account without my knowledge in time, if ***** should happen? They said if I want my smses again, I must go to a branch to opt-out. I didn't agree in the first place to opt-in. Now I must go stand in a que for 2 hours on a Saturday to opt-out for something I did agree to. This is very unfair. I think there must me a way to opt-out without going into a branch. If you can opt me in without going into a branch, you should be able to opt me out as well. Why have notify me if you are not going to be notified? I want my sms notify me back please.
