COX EMAIL HACKED ONCE AGAIN

My Amazon account was hacked again through my Cox email. This is the 4th time it has happened over the past few years. I have 2 factor authentication set up with Amazon  but they bypass that & click forgot password enabling them to get in through my Cox email account and then they change the password. I have changed email accounts & passwords numerous times to no avail. Looks like it time to use a different mail server since there's no security with Cox anymore.
