For future reference, I'd always try and talk to the hiring manager and/or the person you'd be reporting to (if they are different) to see if there is a good personality fit. Ask what a typical day looks like and it will get them to start opening up about the position and what's to come. That might be projects or how you'll be mentored or anything to get you up to speed. Like was mentioned, get everything in writing and if you emailed the recruiter, show it to your new boss and explain your expectations for this position. It might be a shady recruiter or a misunderstanding that got you here. All industries are small and everyone important is never more than a couple of degrees away from the person you could have burned. I'd give them a chance to make it right before you leave, if only so you can tell the next place that you gave them a chance to make the mistake right, it will show maturity and give them the feeling that you're level headed and that they would want you to work for them.
