I have had this happen three times over the last two weeks all on Amazon and while I am unsure if this is a problem at Cox’s end it seems that my Cox email accounts are a factor. In the end I changed my email account details with Amazon to another provider and the problem seems to have gone away. I could not understand how the perpetrators were able to bypass the two step verification but they were and they changed my password with Amazon.
I have fully scanned by computers using McAfee and they show that they are not infected. I am also sure that I have not been the subject of a phishing email.
