E-mail hijacked
I have been using yahoo email for years without incident until recently when I received an email from Yahoo on 8th Nov 2014 on an attempted log in from unknown device from Nigeria, after which there was no more incoming mail.
I then started to receive calls from my friends that they have received my email telling them I was stranded in China and needed help. I went in and looked at my mail box but have seen no activity of such. I have also attempted to send test mail to myself but did not receive any.
I believe my email has been hijacked for scam and would need your help and advice on what to do. Can you help in this case? Please do not send mails to my yahoo mail address as I am not able to receive it.
