It is American Red Cross. I ended up in the E.R. the last time I donated with dehydration and chest pain. I left with a $1,700 medical bill. I can't afford for that to happen again, so they need to stop calling!!!
So, you volunteered to give blood ended up in the ER with completely unrelated conditions.....good thing the gene pool can't spread with blood donations.
I have already had to block 3 of their numbers this will make the 4th. Crooks do this, keep changing their number and keep harassing you after you tell them to stop.
