Dear Xfinity, please catch up to optimum speeds

I am in xfinity area and I have a $15 internet plan (essentials something or other). It gets me 75Mbps

My parents are in the optimum area. I was helping them set up an optimum $15 plan

Turns out their service (same cost, $15 all-in) is 100Mbps

I respectfully request for xfinity to match the competitor's value.

Thank you
