<human>: I haven't been in a Best Buy for nearly a decade, much less even made a purchase there. However about two weeks ago I went in to "check-out" an item that I liked and decided to purchase it. The woman who conducted my transaction was courteous, and offered me reward zone membership along with various other things, to which I replied "No thanks" and went about my day. Transaction finished (or so I thought)

Today, I got a Best Buy credit card (drawn on HSBC) bill in the mail for over $1,000 and my heart sank. The bill shows a purchase for "computers" in Pueblo, Colorado. I'm not sure if the item was purchased in that town or if the stolen information was transmitted to someone there. I've never been a victim of such a thing and am generally very careful with giving out my information. So naturally I'm worried as to how this could have happened! 

It could be purely coincidental but given the timing of this, I am almost 100% convinced that an employee was behind this. How can I find out? I understand that for a card to be opened my DoB and full SS# is required, but could someone open one with the information provided at the time of purchase or return?

Can you summarize the given text in a few sentences?
