Just got a call then they hung up very quickly.

Same. Call from Tuttle, OK.  Immediately hung up.

Called but didn't even ring and immediately hung up. Who is this?!

I've received two calls from this number in the past week so I decided to call back it was an automated woman saying I had won a 100 dollar giftcard redeemable at Walmart, best buy, etc... I'm pretty sure it's just a scam/telemarketing.

I received one today.  they hung up after I said hello. shows up as tuttle, ok
