Who called from 7866071803

I actually called back. Asked to be removed from their calling list, and they hung up.

It was Lisa from rewards redemption.

Around 7:00 p.m. This number called. My phone rang twice and hung up. No message.

I got a call from this number at 5:43 p.m. I didn't answer it and they didn't leave a message. I won't call the number back but I'm wondering if its someone with my personal information to see if this really is my cell phone number so they can use my SSN and stuff. I was recently hacked. What do you think?
