Spam call from a charity; it is fake, therefore don't answer. They place numbers of an actual person who answers over voice mail or no answer and continue to call because they 'know you're there' so to speak.
Called; left no message. I will not answer and you are not bothering me. I have the volume on the phone ringer on "off". SO call away! I am not answering to this number or any other of the 251 and 205 numbers you are using. Have fun.
