Who called from 6362492734

Rang twice and hung up. I don't have a clue as to who these people are

Just got a call from 636-249-2734 on my cell.
No message left.
Called back, sales scam for $100 voucher.

No Message left. Called back and auto message said they were "Reward Redemption" and that I recently visited one of their affiliated websites or stores, and they offering me a $100 voucher to varies stores like Best Buy, etc. Wanted me to press 1 for "yes', or 2 for "no"..... didn't trust it, hung up.

One ring, hung up, no message left....

It didn't even ring, my Fitbit told me I missed a call. I do NOT answer calls to unknown cell numbers.
