Absolutely useless service

So I replaced my old phone with a new phone and what should have been a painless experience turned into drama. On the new phone the banking app will not run. I log in with my username and nothing. Looked at FNB FAQ, nothing, user their secure chat, Useless and once I spoke to someone, he could not help and dropped the conversation. I had to start it all over again without success. Then I decided to call their mobile call centre, got cut off during the process, called them back, spoke to a person after waiting quite a while. Then this person mid way, cut me off. Fast forward to the afternoon, my credit card is blocked and I get a message, call the following number for assistance. Once I speak to someone, oh we cant help you, go to a bank branch. The whole reason I have online and mobile banking is to make things easier. Not more difficult. FNB, you are flippen useless and serve no purpose in the banking world other than infuriating and slowing life down.
