Just a note.
We recently had a card number linked to our acount stolen online somehow. Luckily I cought it in time after ‘only’ $1200 dollars were charged. I had the card canceled and the bank’s anti-fraud department reimbursed the money. But I had to go around and change every account that had auto payments linked to that card and set up new payments with a different account. Check your bank account at least a couple times a week.
