FNB banking app not user friendly!!!!!!!!!!

As a new client I find their App not user friendly. I tried to update the limit on my banking app & I could not even do that on my own it said I needed to verify my device.. Being new to the bank I was told by a consultant that I should verify my account on my labtop, I told her my laptop's in repairs & I am only using my cell phone to do all my trnasactions & work, I asked her if she can assist me & she told me to go into the branch & then said no I cant go into the brnch.. This is so frustrating & annoying because I use my cell with my other two diffrent banks I bank with & I can update transfer & do all my stuff effortlessly... & to think this is my business account with FNB.. Utterly dissapointment... "FNB how can we help you" YOU CANT!!!!!!!!!!!
