I have a very strange case for one AMEX card cancelled about 2 years ago.
I find it was used in the past days by someone and 2 transactions went through in Coles.
Some other transactions didn't go through (not sure why)
AMEX is fine as they will refund the money to my cancelled card…
Very strange, as I thought it is cancelled, why can it be used by someone else?
I no longer have the physical card as I threw it right away 2 years ago….
Are you sure you had cancelled cards?
