I'm also a UCLA med center patient- but these guys called me at 10:40pm on a Wednesday night!!! Unbelievable. The number was placed in my blocked list.
Calls repeatedly. Quality Data Management. They have my name and may be to follow-up on my mother's hospitalizations and quality survery. VERY annoying. They do not leave a message. I have no affiliation with UCLA.
They keep calling. I'm in Boston, so California and/or UCLA has nothing to do with this. By the way, they just called at 8:23pm. No message left...ever. But very nervy to call at this time.
