Would you pay this carrier?

Long story short I had a shipment that picked up 8/27 and needed to deliver on 8/28. Receiver is closed due to the holiday weekend 8/29, 8/30, and 9/2. AL to IN, 630 miles, dispatch gave DEL ETA for 10am 8/28

My T&T called this morning for an update, dispatcher on the line stated driver was on site for delivery at 10am, shipment marked on site at DEL.

T&T emailed at 2pm to make sure that everything delivered and get the POD, dispatch said that the driver wasn’t on site, and that his ETA is 6pm.

He claims that he called the receiver and they close at 5pm , even tho RC says 7-2pm (still wouldn’t of helped if they closed at 5, he gave us an ETA of 6pm) and demands we give him $500 a day since he now can’t deliver till Tuesday. He said it was our fault we didn’t tell him about the closure Thursday, and Friday, but i know for sure my coordinator did and regardless, this was scheduled to deliver today.

Now he’s threatening to report me unless I give him $500 a day. What would you do?
