expired listing

[Isaac Kaai]

Well I'm new to this ,and my name is Isaac , well just got my hands on some expired listings and i am don't know how to contact the home owner, the agent didn't give me the no#. Properties is in great condition move in ready but have no way of contacting them. What should i do, don't want to lose out on a great opportunity. Is there anyone in the downtown area of San Diego who could help with knowing how to get in contact with home owner if the agent don't give the no#. Help .
