Spam call?

I got a call claiming to be Xfinity saying: 

Hi there. I'm calling you from Comcast Xfinity to let you know that your existing account is qualified for 50% off in order to available discount. Kindly call us back at [Edited: "Personal Information"] from 8 a.m. To 5 p.m. Pacific Standard Time. Thank you and have a great day.

I assume this is a scam?
