Even if you haven't done the ALS Ice Bucket Challenge yourself, you may know someone who has. Love it or hate it, it's huge and criminals know that too.
Heather Clyne's aunt died from Amyotrophic lateral sclerosis, so she was more than willing to help raise awareness by donating and recording her own Ice Bucket Challenge video.
About a week after she posted the video online, she started getting calls from an unknown number.
When she finally picked up a man on the other end of the line said he was with the ALS Association and told her she hadn't done the challenge yet.
"I said I did complete the challenge and they were like, 'Well dumping ice over your head doesn't raise awareness or save people's lives, money does,'" Clyne said.
She said the caller started demanding money and she hung up.
After researching the number she found it was attached to various different reports of scams and phone pranks, now she's worried calls like this may scare people away from donating to real charities.
"You're taking away something that could potentially save their lives or their children's lives and it's not fair," Clyne said.
Never give out financial information over the phone to someone you don't know. If it seems suspicious, you can hang up and call back the organization directly to double check if it's legitimate.
