got this private parking PCN due to delivering..

[cringepcnskekw]

Was parked here to do a delivery to a customer who I thought was there, but ended up actually not being able to find the customer at all, once again like my other PCN in the shopping centre, I couldn't find the customer, spent extra time to find them to not have to go back to the warehouse, I'm wondering if there's anything I can do, or can I just ignore this until the potential letter before claim?

I have no intention of contacting or paying until I get the letter before claim/judge thing as well.

Cheers
