FNB / DHA: Why offer a passport service that can't be delivered?

The DHA website says I can book a visit to complete my passport application at my bank. So I tried to book at FNB Lifestyle in Centurion. No bookings available. I tried FNB Merchant Place, FNB Lynnwood and FNB The Glen. No bookings available.

Why offer the service if it doesn't work?

I called FNB's numbers for these branches: *** - No answer, call died. *** - The phone was picked up and put down. *** - The phone was picked up and put down.

Pitiful.
