XFI Complete Increased Upload Speeds

Hi!

I received an email from Xfinity a few days ago saying: "Now get up to 5-10x faster upload speeds. We recently enhanced your network to bring you our fastest upload speeds ever. Upgrade to xFi Complete so you can do more of what you love." In order to get the increased upload speeds, I'm supposed to get XFi complete. However, I'm not planning on getting it if I don't actually get the upload speeds that are advertised. I called the 1-800-XFINITY support a few times, but nobody seems to know about it. Can you please check whether I am eligible for the upload speed increase or not? 

Thanks!
