Called my cell number (which I've never given out). No message. Blocked!

I actually answered because I was anticipating a long-distance call, but the guy started saying something strange about a package he'd sent me, so I hung up immediately.

I also answered because I was expecting an out of state call, but it was someone who was talking about how I had been selected to win a vacation contest. I told him I didn't have time for whatever it was that he needed from me.

I answered as well. The man said I had won something and asked if I remembered signing up. I said no and hung up.

Answered n they hung up so I called back n my phone say can't dial number please check number
