Most Annoying...EVER

There is some annoying company out there bothering me with recorded message calls. I got two calls Thursday afternoon, and one Friday afternoon. I find it so annoying to answer the phone only to hear a recorded message. This one goes something like, "Hi! This is Nina with ___ Resort Services calling to tell you that you have been selected to receive a 4 night carribean cruise valued at 6,000 dollars for only $399! Press zero now to be connected with an operator." The first time they called, I hung up. The second time they called (remember it was the same afternoon) I pressed zero so I could get my number removed. You will not believe this, but I held for 30 minutes and finally hung up. Now, I did not just sit there holding, I rigged the phone to where I could hear the loud horrible tacky elevator music while I did other things such as clean, play with Ava, etc. Then when they called me AGAIN Friday, I pressed zero again and this time, I held 40 minutes! And after 40 minutes, it disconnected on its own. I have yet to talk to a real live person. I already have it all planned out, if I do get to talk to "an operator" one day. I'll act so excited to be getting this dream vacation at such a steal! I'll get the person's name and phone number, just in case we get disconnected (or in case they hang up in my face when I start to tell them how much I hate the calls I've been getting). I'll find out all about what company this deal is from, so I can contact them as well if need be, and then I will lay into them for disturbing my afternoons with their stupid calls. But part of me wonders if this really is a sales call. Maybe it's come strange psychological experiment where they call random people and see how long they are willing to hold...never intending to have anyone answer. I'm probably the record holder by now.
