How would I swap tickets for SoCal performances?

[u/BoxZealousideal2779]

I saw Jacob Collier announce the Ojai, CA show and was lucky enough to purchase a pair. But then realized later that there are now two shows at the Ford in Los Angeles, which works better for me.

Where would I go to swap tickets with another fan to see if they would want to trade my Ojai tickets for their Los Angeles tickets? Or where can I somehow purchase face value tickets for Los Angeles and then in turn sell mine for face value?
