Just got a letter from Lloyds that due to a small fraud risk, they are replacing my Amex (but not my Mastercard). Did anyone receive a similar letter and is this the way that Lloyds takes your Avios Amex away? I did purchase a ticket on BA in August during the hacking scandal so I can understand that there is a risk but I would not like my Avios earning to be taken away prematurely.
