A while ago I got an e mail from Ebay advising of suspicious activity. I logged in and changed my password and noticed they had tried to buy an iPad. It hadn't been paid for so I contacted Ebay and they cancelled my order. I wondered what the person doing this had got out of it but thought nothing more of it until now.
I just went to order something and noticed that the scumbag had changed my saved address . It still read as the first line of my address but then extra details added in plus they changed my postcode.
I never noticed this on the last order I made so my last purchase has been dispatched to their address.
