Who called from 3604601821

as soon as i picked up the phone they hung up

I got the call about 5 minutes ago.  Same results.  One of the only places I have given my number is to Sears when I got tires.  I hope they didn't give it out.  Nobody else except friends and family has my cell phone number.  I was reluctant to give it to Sears and wish that I hadn't.

didn't have my phone on me. Found a missed call from this number, no msg left

I didn't have my cell phone at the time. They called 5 times over 3 days. I called back and it was busy. They didn't leave a message either time. I googled the number and found this

Just got a phone call from 360-460-1821 on my cell and when I answered they just hung up
