buyer - international address, suspicious

[l.willi_50]

Concerned my account has been hacked as I did not tick international postage yet a buyer based in USA bid and bought 8 of my items tonight. Yet to pay. 

Is the account safe? 

I have cancelled the order and changed my password.

Your sold listings I looked at said UK postage only, the buyer may have had a UK delivery address if you'd given them chance to pay.

Thanks for the reply.
Their delivery address stated LA.
