Yahoo verification code not received

Hello,
Hi, I am trying to access my Yahoo mail but need to reset my password. It is supposedly sending a verification code to my gmail accout, but I am not receiving it. For gmail, I have tried multiple browsers, rebooted and logged in again, verified that may mailbox is not full (I receive other emails fine), I have no blocking or filtering on my account, I have accessed https://mail.google.com/mail/u/0/#all to make sure I am not missing anything, and have checked my spam folder.

I tried paying for technical support but it is not available in Canada and can find no way to contact Yahoo for support since I cannot login to my Yahoo mail.

Any advice?
Thank you in advance
