I wouldn't have noticed right away, I check on-line only once a week at most so thank you for the heads up.
I have been the victim of a scam before and I would have defied anyone not to have been taken in...they are very sophisticated (it involved a fraud of several thousands but we were re-imbursed almost immediately). My husband who is more astute financially than I am has also fallen foul, only found out as the bank called as there was suspicious activity on his account.All he did was pay for something on-line....within minutes they'd scammed hundreds. No-one is safe.
You're not a dullard by any stretch of the imagination to be caught out nowadays.
