ONCE AGAIN NO SERVICE FROM FNB

Once again my FNB App is blocked by FNB for some unknown reason and it is not due to the incorrect password. I had the same problem over a month ago. My FNB App is blocked but it tells me to log on to another device which in turn tells me I must log onto my FNB App ??? After unistalling and reinstalling the App and having to go to a FNB atm to verify the App about 4 times I eventually got a very limited use on my App. I must have FNB Customer Service about 6 times could not get through due to busy lines and when I got through I was simply cut off by the the FNB staff member clearly not interested. I latter got through to somebody who requested that I take s screen shot of the message on my App and and email it to them and that they would refer it for further assistance. NOTHING CAME OF THIS AS EXPECTED FROM FNB. I got full functionality back on my App about 2 weeks ago and now I am back to zero service from my FNB App. I HAVE NEVER EXPEFIENCED SUCH INCOMPETENCE STJPIFITY AND DISRESPECT FROM MY BANK IN THE UK TO WHAT RECEIVE FROM FNB. FNB MUST BE THE PINNACLE OF A THIRD WORLD BANK. I bring foreign investment into this country every month and I am a registered tax paye in this country and the UK. MY ADVICE TO ANYBODY WANTING TO BRING FOREIGN INVESTMENT INTO THIS COUNTRY DO NOT USE FNB. As with most of my complaints to FNB, I have not received any replies from FNB, so I don't expect and response from this complaint.
