Who called from 7708524544

Please remove me from your call list.

Really?

Called you by an alias YOU have used, and they sound fishy?! LOL  It's the Red Cross...

Red cross harassment

Red Cross DOES NOT monitor this page nor could they possibly know your phone number from this page.
If you do not answer they do not know you are annoyed by them ... Answer, listen to their introduction and POLITELY say - "I am no longer interested in being on your contact list, can you please remove my number?" ... They will ... They end ...
