"How can we NOT help you" - worst customer service I've received from a bank

I have been receiving shocking customer service from FNB. I have recently changed mobile service providers, and have not been receiving OTP's to activate my FNB since mid-December.

I have been on the browser-app with their 'in-contact' service, receiving useless once-off information from agents who don't understand my query, and then get put to the back of the queue, time after time.

I have been on calls, being sent from one department to the next, with lines dropping, and automated requests asking for reference numbers I don't have, just to be dropped as well.

I have been sending emails, receiving automated responses about a 48 hour turn-around time, and never hearing back from them again.

I just want to access my FNB app, as simple as that. "How can we help you" is definitely not something I perceive as a truthful slogan anymore.
