Sorry, it just makes me chuckle a bit. I actually work for a company similiar to summit, except we only deal in BMW's. One piece of important advice I would give is this. Always talk to the same person. If you call in and just talk to anyone, you never know what kind of answer you will get, especially if it wasn't that particular person's sale. Don't get me wrong, I would be hounding them too, and if they have given a bogus tracking number, I would certainly be asking for a supervisor. But did they actually charge you for the second set? If not, they will likely need a return tracking number on the first package before they will release the second package. This is pretty common mail order parts stuff, nobody gives away free product unless it's so cheap it isn't worth the return shipping.
