Never give them your phone number. I in the past donated every 2 months. One time my hemoglobin was too low and I was denied. It was my last time donating to them. I received constant phone calls on my mobile and home phone about donating. I have asked so many times for them to take me off of their list because I am so tired of being harassed. I just got a blocked call from them but I still have to erase the message that they leave despite my pleas. I will start writing a negative review for every call I get a in different sites. Let's see how quickly they rack up. I will still donate when I hear of non Red Cross donation drives, but never again will I donate to them. You shouldn't either unless you like being harassed
