How to get my free Xfinity xpods

I saw a promotion from  Xfinity that if I upgraded to 1 go speed or higher I could get free xpods. I got the new modem. Nobody at Xfinity has a clue what I am talking about. Should I just go back to my old speed and order a mesh system from Amazon? Why did Xfinity offer a deal that I can’t seem to get? I don’t mind paying for the faster speed but the only reason I did it was to get these range extenders.
