I have already binned the email that I received about this from Amazon this morning warning about this scam and warning me not to "press 1" or enter into any dialogue.
They also warned about a scam where phone calls were being made claiming that "my" Amazon account had been hacked and I had been signed me up to Amazon Prime and that if "pressed 1" and I supplied my bank account details Amazon would arrange a refund.
I guess the scam artists are putting in an extra effort to pull the money in before Christmas.
