I don't know if I ruined this load or not

So for my whole trucking career I have been a dry van driver. Today, I get a load assignment for Costco. Not much information about the load at all, in fact there's none besides where I pick it up and where I deliver to. Also the fact that the a appointment was for yesterday afternoon.

So I get to the Costco DC. Turns out it is a reefer which I have never hauled before nor cared to.

I ask questions and the lady pretty much assures me everything is OK and it's simple. As long as they green light stays on you have no problem. She says the reefer has enough fuel so everything is good. The load is going from Dallas to Tulsa.

I get to the Costco in Tulsa, approximately 24 hours after the original appointment time.

They tell me the trailer is warm. "64 degrees". They come outside take a Pic of the little temperature Guage or whatever. I ask her if it was correct she said it is. So I'm just confused right now. I have no idea how this happened.

Edit. The reefer Guage is on +13

 

Grocery. Produce and meat both

 

Currently they are unloading some of it that is still cool(below freezing or below 40). I'm guessing the stuff that they say isn't good they will put back on the truck

 

The load was like 11 degrees when I got it. When I got here they said they took the temp inside the truck and it was 64. However alot of the stuff on the truck is still at right temperature or below freezing. I just went outside and looked at the temp it is now at around 34 degrees. I'm guessing because they have the trailer door open unloading.
