Cannot receive Microsoft account verification code in my Cox Webmail

I have been trying for over a month to receive a Microsoft security code via e-mail.  There is a post from two weeks that has been closed, that clearly states this has been escalated, but this is not still resolved.  I NEED TO RECEIVE A SECURITY CODE FROM MICROSOFT VIA MY COX.COM E-MAIL.  Otherwise, I will have to format my computer and lose precious information.  Please help me with this.
