Hangs up and no answer when returning the call. Who is it?

Yes, this number calls every week or two.  Never leaves a mssg.  Very annoying.

wont identify who it is- rude

Caller said that my wife and I both signed up for a contest. Not that I know of as I don't do that as I know beforehand what the deal is. They want to send me a key and it's it fits in a new truck, it's mine or $20,000.00.
I let her know that I'm now on a fixed income and can't afford a camping membership nor am I into camping. They want me to drive many miles to listen to their speil. No thank you.
The last camping membership that I signed up for many (25+) years ago we ended up by suing the place and won.
I think that they're based out of Davison.
