I've had numberous calls from this number.. finally today I answered it.
As stated below, no one said anything when I first answered the phone, finally someone came on.
I suggest playing stupid with them... make them repeat what they are saying, tell them you don't understand what it's all about and why are you "searching for me?" After all she said she was from the cancer "research". I don't donate money to anyone except for the local children's hospital, where I know how the money is used.
