called home number, the call was answered, asked if this is a certain family member's name, but then pretended to not hear me when I inquired "who's calling". No response to my repeating "hello?" numerous times.

Called and did not leave a message. I do not know them and did not ask them to call me.

One website I used to search where the number is located, zeroed in on the Mirage Hotel and Casino in Las Vegas.  I'm assuming they are trying to give away another 'free vacation', and we know nothing is for free.

Trying to sell me a vacation in Vegas. When asked to take me off their call list, the caller called me several obscenities until,I hung up on him.

Literally the same thing happened to me on the 29th...The caller said unforgivable things about my wife.  If anyone has any information about how to find the business responsible please reply to this thread.
