Hard Inquiry on my Credits even when I ask the agent twice to not do that , how to escalate get corrected and ask for the compensation

I  signed up for xfinity Mobile today, in the process i was asked to provide SSN number and the agent told its going to be just identity check and not a hard check. 

I was shocked to see an alert from credit monitoring platform that I got a hard hit. 

A lot of agent, I'm trying to speak do not understand the meaning of it. But I got my credit application impacted, I need compensation for it and also need to get that fixed from Comcast.
