I am getting calls from this number also. They stayed on the line long enough for a short vm recording and it sounded like a call center. I'm not answering or calling back if they are not going to leave a message.

This is the American Red Cross calling to schedule a blood donation.

American Red Cross 510-594-5113

They keep calling. Makes me want to not give my real number if they are going to harass me for blood or donations!

They used to call me about every other week, reminding me that I can donate blood again & practically begging me to make an appointment. I understand that they are at a constant need for blood, but I don't need someone calling me ALL THE TIME to remind me. I will donate in my own free time whenever I want to.
Also, ever since I've stopped answering their calls, they have been calling me every day. Quite a bit annoying.

These vampires want my blood
