MonsterRentals.com Paid Membership for Fake Service Santa Monica California

I signed up for a membership with MonsterRentals.com to search apartment listings in the Los Angeles area.  

I've called about a dozen listings on the website.  Each call has resulted in one of the following three results:

1. The phone number listed has been disconnected or goes to a recording service that says the number is now "unattended."

2. The phone number is completely wrong and I've ended up calling someone who isn't involved in listing an apartment in any way.

3. The listing I was out of date and the realtors were shocked I was still calling about it and asked me where I was still seeing the listing online.

I feel completely scammed by this service.  There is no accountability and no proven method of contact information for reaching them.  Avoid this website at all costs.
