Nonexistent service from FNB

Called in and kept getting referred to the banking app that I don't have. Went to a branch and was asked to call the same number - got a little bit further with their assistance, but still left the bank without a resolution. Sent email to their complaints department, received a bunch of computer generated responses, and an sms saying that they tried to call (must have been a phantom call), then they disappeared. So fed up.
