my yahoo email has been hacked and the username and password are no longer recognised

[Bobbbyh]

My Yahoo email has been hacked. I am no longer able to sign in to my account as the username and password have been changed.

Non of the recovery methods work as it seems all details have changed so recovery messages are not received

The username part of you login can not be changed, so have you tried resetting the password so you can get login access back:

Then login to your online account:

https://skyid.sky.com/signin/email/

Go to Settings > More Settings > Filters and remove anything that you did not setup.

Then go to Settings > More Settings > Mailboxes > Your email address > Reply-to address

And again remove anything here that you did not setup.
