Is this a legitimate email from comcast or its affiliates? Are you outsourcing?

I, like many other people it seems, have received an email after filling out a customer feedback survey. This survey was after using a chat service via medallia. 

I tried calling Customer Security Assurance but the person I spoke with was ultimately only able to give limited details, had never heard of medallia, and there was no one else there I could speak with…

I have since changed my passwords but even that seemed to give me problems at first. 
What follows is the email I received:

Following up on your recent Xfinity survey

Hello XXXXX,
 
My name is Bikramjit  and I work in  at Comcast. I want to say thank you for completing our survey about your experience with Xfinity.  It sounds like we didn’t meet your expectations, and I want to apologize for falling short.
 
I attempted to reach you a few minutes ago. Your feedback is very important to us. It's essential to helping us continually improve the Xfinity experience for customers like you.  If you are willing and available, I would like to schedule some time to call and speak with you about your experience so we can make improvements. Please reply to this email with a few times that work best for you.
 
I look forward to talking with you.  We always want you to have the best experience possible, and we thank you for your trust and for choosing Xfinity.
 
Kind Regards,
Bikramjit

I did not click the unsubscribe button and do not recommend anyone does without first checking it with a comcast employee for this.
