Please note the first sentence: " If you see a Yahoo customer service number posted online, it isn't Yahoo support." and, one click further "Remember: support from Yahoo is always free. If you call what you think is a Yahoo customer service phone number and are asked for credit card, banking, or account login info, end the call immediately. Handing over this information could compromise your account and your financial information."
Don't fall for those scams.
Note: this is declared a link free zone. Any post with links to such fake support sites will be deleted.
