I got this number, too, several times they've called me. This last time they finally left a message saying they were from Kaiser saying they 'wanted to discuss health opportunities' with me.At 7:00pm. Kaiser has never called me from this number nor said anything like this before. The number that came up on caller ID was 310-482-2971, but when the lady left a message she left a 855 number.. Wtf. Scammers!
