Yahoo is warning its customers about a scam involving Yahoo customer service. Certainly with the disclosure over the last couple of months that a billion people had their personal information stolen from Yahoo, there may be many people with a need for customer service from Yahoo, however the scam involves a Yahoo customer service phone line. Scammers are posting telephone numbers for Yahoo customer service and charging people for their services where, at best, they do nothing for you and, at worse, they steal the information you provide when you speak with them to make you a victim of identity theft.
Yahoo only provides customer services through email, chat, social media, help articles or its Yahoo Help Community forums. They do not provide customer service by phone and they never charge for customer service.
