Last night I tried to take cash from ATM to pay for DS1's guitar lessons (we can't find any cheque books after the move). ATM wouldn't give me money - said my card hasn't been activated. Amazon refused the same card when I tried to make a payment. Logged into online banking and the account attached to the card wasn't there! It is our joint account with all the money left over from our sale in it. Needed for new furniture and to pay off a loan.
Rang bank and got put through to woman in the 'fraud dept'. She only wanted to check my last few payments to ensure they were legit. Apparently my card use pattern had been similar to that seen in card fraud. I can only assume that it's because I've been spending more for the new house.
I guess it's a good thing they were vigilant.
