ouch, a sad story, to say the least!
I think I can bring my own experience, here in Italy.
In july (late July to be fair), I've bought an M8 from a local dealer (I've could have saved a couple of hundreds euros buying online from some respectable shops, but I've preferred to "see my dealer in the face". The story tells me I did right).
After some days, I realized it had problems with focus and with frame lines - they didn't change when mounting lenses). It wasn't easy to spot it, as I'm a Leica newbe, but eventually, with the help of some friends, I brought it back to the dealer, pointing the problem out.
He looked at it, he consulted some "leica-gurus", and decided it had to be sent back to Leica.
Actually he didn't sent it to Leica Germany, but to the Italian Leica importer (Polyphoto) - as he was supposed to do.
I suppose he let it sit there a couple of days, before shipping it (he had to contact Polyphoto in order to arrange a shipment, I imagine).
Well, as soon as Polyphoto saw it, they send back a new M8 as a replacement. It didn't even need to go back to Solms to be "visited".
My new camera was back within two weeks.
I must admit I'm a satisfied Leica customer, who received a great post-sale service.
(we may argue that even two weeks is not quick enough for a professionist, but... for a small company like Leica - and compared to you hodissey! - it's acceptable to me)
This just to say, it's strongly depend on the local dealer/HQ.
Consider I'm in a very small country (if compared to USA, at least) and, I don't have any sale data, but I'm sure they sold less M8 in Italy than in the USA. We could expect, then, a worst service in here, but no, it's a great one, and I'm happy of it being so. (and to have chosen the local dealer for buying it).
Bottom line: it seems that the Leica USA/your dealer is to be blamed for your sad story. (not that this change much, especially for you!). And while this isn't the first story of this kind I've heard (well... read) about, I'm confident Leica is putting a great effort in the after-sale service, at least in some part of the world.
I hope you'll end up with everything back ASAP, and wish you good luck with your "new" camera...
