FNB Cellphone Banking

I've had a problem with my FNB cellphone App. This has been going on now for 48 hours and FNB hasn't resolved anything. I have patiently been waiting and it's now 49 hours and still haven't even had anyone from the bank phone me to see if they can help. Can't believe the services I'm getting from the bank after over 30 years of banking with FNB.
