Michigan Blood. Not a robo-call. Asking you to donate, they can provide info.
However I will note they have called me every few months for years and it took them a quite embarrassing amount of time to reflect my address change.
I got a call from this number last week and another one today. It is MI Blood, I've told them about 3 times now that I moved to CO back in March. Last week when they called the woman told me they had a trauma patient in the hospital in desperate need of my blood type and they wanted me to come over ASAP if I could to donate. Awesome call to get as I was driving into work 1300 miles away. JERKS!
