Dealership won't stop harassing me!

I was browsing online and saw this awesome Acura TLX with only 2,000 miles on it. I immediately clicked the link so I could find out more information and schedule a test drive. I entered my email address and phone number so they could get ahold of me right away. About 10 minutes later I got an email saying that the car WAS available and asked when I can come see it. About 10 minutes after that I got a phone call DURING work. WTF!? I was busy but decided to answer anyway just so I could yell at this stealer trying to spam me with phone calls. He said he was following up with his email to try and see if I had any other questions about the car. I was furious. I'M JUST LOOKING ASSHOLE! What kind of lawyer do I need to sue for harassment from these thieves?
