Cant get hold of FNB because of verification

I called FNB on the 29th of April because i wanted them bundle my credit card and debit card, i spoke to a consultant who helped me and said it was all sorted, the moment i put down the phone i could no longer get onto my cell phone banking app, it would just lag and nothing happens, now when i try log in it wants me to completely relink my banking app, it wants me to do the selfie option so i do it then it says please wait for OTP, i receive the OTP but it never gives me the option to enter it, Now today I'm trying to contact FNB and it doesn't matter what department you call the automated machine wants you to accept the verification on your cell phone banking app, HOW AM I SUPPOSED TO ACCEPT IT IF I CANT EVEN GET INTO MY APP and it will not send me to a call centre agent !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! this is very frustrating cause how do i get this problem sorted the automated machine isnt going to help.
