Just received an email From Amazon.co.uk thanking me for my order and telling me it has been dispatched. Only problem is I didn't order anything and none of ny family has either. I know I can reutrn it but I'm curious as to how this could have happened and how to prevent it happening again. I have been a customer for years and never had this problem before. I don't check my emails every day which is why I didn't spot the acknowledgement of my order before they posted it.
