NO VERIFICATION CODE OR ONE TIME PASSWORD

For the past few days I have wasted hours and have been going around in circles with Dell Tech Support and Dell Customer Care Department, trying to sign in to my Dell account through Dell.com as well as the utility app Support Assist.  Technical support referred me to customer care who told me he could not find my email address, although it was still in their system.  How else would the system respond to sending me a verification code or one-time password, which I never get!  He told me to create a new account, which I wasn't able to do because the email already existed in their system.  THIS HAS BEEN EXTREMELY FRUSTRATING AND TIME CONSUMING!!!
