Yeah, they contacted me all right, by letter. i have paid the ******** the money they asked for.
I think the scammers made an error. Rather than offering a refund, they should have demanded a sum of money, say £65.65 by 31 Jan or the possibility of a £100 fine. That way they would have got both the payment details and 65 sheets up front while you tried to avoid the fine. Given the 31st is a Saturday a good time to send out the emails would have been the 30th.
