Panera Bread review: service

I called in a carryout order on 2-7-20 and arrived a couple minutes before I was told it would be ready. I paid for my order at the front counter and was told to go to rapid pick up. I waited about 15 minutes and asked when my order was going to be ready. I gave them the name the order was called in under & they couldn't find the order. I gave them my receipt because they were asking what I ordered. The manager came around and explained that the girl at the register wasn't aware she was suppose to give them a copy of the order so therefore they didn't even know I was there. The manager gave me 2 cookies & a drink for my trouble. It took 25 minutes to get the order that should have been ready within minutes upon my arrival. I ordered 2 sandwiches and one was missing the avocado & cheese & the other was missing the cheese. There was barely any meat on the sandwich also. When you are spending $21.00 for 2 sandwiches they should be made correctly and not missing anything. I feel I should receive a refund. I do not have the receipt because they kept it when I handed it to them so they could make my order.
Thank you,
