Premium e-mail account on Android
I paid for premium e-mail account on Android but still getting loads of SPAM & advertisement mails daily. Pls activate the premium feature or refund my money.

The Mail Pro subscription removes ads from your mailbox. If you’d like to stop receiving marketing emails from Yahoo, please go here: https://help.yahoo.com/kb/account/sln5154.html
For spam, the best you can do is to report those messages as spam. (https://help.yahoo.com/kb/SLN3402.html) Depending on the number of similar reports, our Anti-Spam filter may take some time to react and start actively blocking them from reaching you.
In the meantime, you can either create filters(https://help.yahoo.com/kb/mail-for-desktop/SLN15994.html?impressions=true) or block those email addresses.(https://help.yahoo.com/kb/mail-for-desktop/SLN16025.html?impressions=true)
