Getting less than 30 mb download speeds but paying for a 1gig connection

Hello, as the subject states I recently came back over to xfinity, but am getting absolutely unacceptable speeds. I'm currently getting 30mb down, which would seem to mean my internet is not provisioned correctly.  This definitely doesn't comply with the FCC's idea of an acceptable threshold for what I am paying for.

I am seeking this to be fixed and also credit for the time I've been paying so far but getting far less than I am paying for.
