Yes Timbo57...exactly the same happened to us ... hence the question.
There has to be more to this than just random spamming and hacks as there are so many people affected here..
Wife's account blocked on 17th June...got access back on 20th...only to discover the Amazon frauds + thousands of spams (?) signing her up for accounts and news letters all over the world.
VM informed us that the redirect was added on 26th May !!! without our knowledge.
Amazon refused to let us have access to the account or to block or close the account because the criminal had added 2 step authentication ...so we couldn't change the password or log on.
Bank cancelled card...Amazon now chasing us for the money from the transactions. Unable to speak to anyone at Amazon + customer service guys on online chat are unable to do anything ...apart from sympathize !
We have responded to Amazon emails in detail but are only getting automated response email + repeated request to pay for the transactions via some other card.
Its all a bit of a nightmare !
PM me if you wish to discuss further or compare dates etc.
In my view there is some sort of organised hacking and fraud going on here...It may be that VM is unaware of this, but as other have suggested the limited password security may not be helping.
I would really like to think that behind the scenes VM has a team busy investigating the source of all these suspicious activities that is causing them to lock access to mailboxes.
