Pathetic App

FNB blocked my new device because I entered a wrong OTP. The error message received was just saying I should use my online banking. Nothing about how long it will be blocked for or what to do to unblock it. Now after attempting several times to sign in, I was told there is a 48 hour block, so everytime you attempt it during "that time", your 48 block will reset. Why could FNB not say that in the error message. Why do I have to phone after them several times only to find that out. FNB your fault is pathethic... why don't you include that in error message. I am without my app for without 48 hrs even though you insist we do everything on our app!
