It's hard to say if they cross threaded the plug trying to put it back in, it's easy to do if a person doesn't pay attention to what they are doing. I do think that if it were already cross threaded in the pan it would be difficult coming out to begin with and they should have stopped there before taking it out and come and told you what the situation is.
But to replace the oil pan the engine needs to be supported from underneath. It looks like the driver side axle needs to come out, separate the lower control arm from the steering knuckle. and then a bunch of engine and transmission supports have to come out. So, this is not just an unbolt the oil pan type job. Unfortunately, it's your word against theirs in this situation. This would be a tough job to do in the driveway, although it looks like it could be done, but you'd have to be extra careful.
And yes, if the drain plug were that loose when you went in you would have noticed oil in your driveway. So, it was either already cross threaded and they took it out that way or they cross threaded the plug, got it all messed up and then backed it out again messing up the threads.
You can call another shop and see if they would try straightening the threads out for you with a tap kit. Depending on how bad they are. That's what I would do before paying $900.00. That's a bit much.
