Who called from 9702894983

Caller comes up from Brush, CO. No voicemail left. Called back and it is an automated woman's voice saying she is from Reward Redemption and has a $100 voucher

Didnt even completely ring once. My screen flashed and I had a missed call.

no message left

One ring and hung up, no voice mail left.  So, I assume it's like many others and a scam/unwanted solicitation call.  Blocked number list gets another.
