I've been getting calls from this number almost every single day, for many weeks. I've never answered the phone. In fact, I've blocked the number repeatedly!, and it still rings through, so assume it is a scam. Caller ID says it's WTD CANC SUP FUND. No message is left, of course, so, again, assume it is a scam. A Google search brings up no result either.
Even If it was legit, (which I seriously doubt), at what point would I expect a charity call to 'NOT' become harassment?
