Received 2nd call from this number within one week. No response from the other end when I answer my phone

Answered today and the man said his name was Kevin from Keller Realty. Said he was calling because I had been browsing trulia, zillow, and similar sites. Asked him when did I ever request info on any of those sites. He was not interested in talking when I started asking questions and said I wasn't in the market for a house. Idiot just phishing. Trying to figure out how he got my info since I'm not a member of any of those sites and never requested any information from them or Keller Realty.

Got 3 calls from this #. Then when He hung up  I called #. No answer.

Called my cell phone first then immediately after they called the house phone so I answered it and there was no one there. As I went to hang up it sounded like a male voice on a speaker phone but still hung up. Once again called immediately back and I didn't answer that time.

It's an idiot realtor from Keller realty at Phoenix
