I've had several of the same emails but I didn't purchase anything and when I check my account there's no record of the purchase.

There are a number of similar phishing emails doing the rounds, trying to get account and payment details. How are the emails worded (e.g. are they personalised, which emails from Apple will tend to be, or something like 'dear customer' or just 'hello'), and did the email have any links in it (e.g. to 'request a refund' if you didn't make the purchase) ? If they are phishing emails then forward them to Apple : firstname.lastname@example.org , and then delete them.

It is a phishing email - it's not properly personalised (it has your last name first), and the 'iforgot.apple.com' link does not take to that page (it would take you to http://sixniner.com, for you to give the phisher your account and payment details).
(As these are user-to-user forums I've asked the hosts to remove your email address from your post.)
