It's from L.A. med center appointment desk!! I saw on another website so I called because I had been waiting for an appointment. The callback number is 855-521-1718. Boy glad I found out....the 855 area code threw me off
This no. just called on my mobile phone again & I missed it. Again, I tried calling it back both on my mobile and on my landline...I get a mess. this call cannot be completed as dialed!
