Today I got a "Service Confirmation" email from an Apple Store. The customer information on the email was my name and address, however the phone number, serial number, date of purchase, and email address were not mine! The Apple Store number is a store in CA and I live in FL. I haven't requested any warranty work from an Apple Store as of today. So I called AppleCare to see what was going on. After some investigation, the rep told me that there were 4 iPhones registered to my name. Not just my name but also my address (one of those iPhones being mine). Im not sure why they would have registered their phones under someone elses name. The rep said it could have been a glitch in their systems. I checked on my AT&T account and there were no additional lines added or anything like that. Should I be worried? What should I do?
