I randomly received a 6-digit yahoo code to my phone number yesterday. And today when I enter my phone number I came to see that it is already registered. I created a yahoo account but I am unable to add my own phone number. I cannot see any way of contacting yahoo customer service other than paid service. But if someone was able to enter my phone number to their account or get my number blocked from the system without my knowledge, it is a serious security issue. Can you please provide guidance or reach me for how i can contact yahoo customer service? If feedback necessary: It is terrible that i see no way of getting assistance on UI in such important matter too.
