Unexpected charge on my credit card

So I just got my credit card bill in the mail earlier today and I see that earlier this month I was charged around $74.19 out of nowhere. Now besides the random charge this doesn't show up in my order history on my Microsoft account so I have no idea what
this is about. I checked my yearly live subscription date and its not until February so its not that and I know I don't use my card on anything other than Microsoft so I highly doubt that someone has my information. So I'm left to believe that this is an error
on the other end. I'm not sure what to do about this. The the support said to get in touch with my billing but I doubt that will help with anything.
