We've just had an order and enquiry come through a ZenCart site against a customer that they have no connection with. Any suggestions as to where I should look to work our what happened?
Specifically, I have customer A who registered at time of placing an order and has never logged in since (the site confirms this). I then have customer B who ordered but came through as a new address for customer A. We then had visitor C who without registering sent a "contact us" email through the site and that also came through as though it came from A.
