What was the reason for parking there, were you loading/unloading or dropping off/picking up passengers?

A disabled passenger was being escorted out of the vehicle and across the road into the bank situated across the road.

Can you expand on this activity, please, because the No Loading restriction bars you parking using a BB, but alighting a passenger is the other exemption that applies to everybody not just BB holders. You seem to be describing "assisted boarding/alighting", but we need more narrative on what went on.

OK, so you received a postal PCN because you drove away before the PCN could be served. "Driveaways" were dealt with in the Traffic Management Act 2004, with the result you have experienced.

As you have a postal PCN, there is no Notice to Owner stage. I suggest you submit reps on the basis I described earlier, namely you were escorting a disabled person to the bank, and found the PCN when you returned. State that "boarding/alighting passengers" is an exemption to the yellow lines. Also state that where a passenger needs assistance to his destination, the driver may assist that person on the basis of "assisted boarding/alighting", and you therefore expect the PCN to be cancelled.
