It sounds like a call center collecting for some charity, probably named American Children's Cancer Fund. You can be sure that anybody calling you is putting all the money in their pocket and giving the charity pennies on the dollar. If you want to donate give directly to the charity and then all of it goes in the right place, not some crooks pocket.
This number has been calling me every day, sometimes twice a day , afternoons and evenings, for about 2 weeks now. The caller has started leaving a message, "Is the lady of the house there?"
Call from AM Child Can FD, 14 calls in the last two days. I am getting calls from two different numbers. One number is 478-239-6669, the other is 478-974-5158. After I blocked the first number, they started calling from the second number, so both numbers are blocked now, but when I look at my call history I can see that they have called a ridiculously amount of times. When I use the block feature on my phone to block your number, the caller hears "This person does not wish to receive calls from this number" then the line goes dead. You would think that after calling 14 times and hearing that message they would stop calling. Don't know if it is legit or not and i don't care, they have been blocked! When I give to a Charity I am going to give it directly, not to some joker that keeps harassing me with phone calls.
