Option to remove spam ads or junk ads..

Today I came across an ad which is spam coming from api.taboola.com in middle of my yahoo emails. when I scroll over to go to my other email, it opens automatically and it shows suspicious IP address and ask me to call number blabla.. I know it is spam but there is no way to delete this "ad" myself. Also when I tried to report this through yahoo support form, https://help.yahoo.com/kb/search-for-desktop and filled in details and clicked
" create request", nothing happens. I am blocked to report this issue properly and also I cannot delete this ad which is concerning to me. I have to deal with this ad which is not safe. Can you please streamline your support system and also help us as users to remove unsafe ads from our email account or give better support phone number so we can Call and explain when we cannot share this via ticket
