Do you have an investigative reporter doing local crackdowns on one of your local stations? We've got one that's pretty good out here, and you can give them something big or small, and as long as it's something stupid, he'll go in with cameras and make the people look like morons. You're right, 5715, 5952, whatever it is, the fact is, it's an oil change and rotation. Oil change places just have somebody sitting in a pit who drops the plug, adds oil, lets it run a second, and sends you on your way. Tire rotation is just a quick balance and rotation, followed by a quick drive around the block, half mile at most.
If they put 237 miles on, something really stupid happened. If they forged paperwork to say it's 5900 miles, even then, that's still 52 miles. If things were slow, we might take it two miles, not fifty two.
You've got a case here though, call and complain to Ford and the Regional Ford affiliates. The BBB is worthless in that people just like to complain to them, and if they have registered with the BBB it goes on their record, if they aren't BBB members, then it pretty much goes nowhere.
edit: Maybe see if your state has a Dept of Consumer Affairs, or Labor board.
