This number calls 1-2 times a week around 8pm. Says they are United blood services, but I looked them up and none of their numbers match this number. Told them to stop calling, but they keep calling every week anyways.
Actually, this IS the United Blood Services outbound call center number. If you don't want to set up an appointment to give blood, either don't answer, or just tell the rep that you don't want to. No need to be a jerk about it.
