Advise on how to deal with the issue of Comcast being issued subpoena for my information

[lc_nab]

I received two documents one via USPS the other via ups, but it was a notice from Comcast saying that a subpoena was sent to them from the court and it stated from who, which is the Dallas Buyers Club, llc. Neither was on certified form, nor I had to sign for it, they where left at my door\mailbox.

I thought it was a scam, but the docket number matches, when I gave it a web search.
