McDonald's

I went to get lunch at the logan ave location in Waterloo, IA this afternoon and paid for a large Double Quarter pounder with cheese meal and received a medium. Was told that my food wasn't ready and to pull forward. When I got to work (2 blocks way) they had given me a medium meal and my food was cold. Even though I ordered a large meal, the fries box of medium was half full. I didn't have time to drive back and get this corrected as I had to get back to work. I have the reciept but it's very hard to read. The authorization number (that I can make out) 394408 and AID a0000003980846? My meal came to a total of $11.44.
