It is not related to Target, I have never been in a Target and I get up to a half dozen of these type calls a day. Most lately seem to originate out of FL, I either reject the call or let it ring, they never a message.
Caller ID said "Network Service" which sounded flakey in Indiana coming from a Florida location. I never answer calls like that figuring if it's legitimate, they'll leave a message. They never do.
