Keeps calling, no messages.

I have gotten quite a few calls from this number in the past few days. Every time I've answered, the line cuts out. No lost signal, just a hangup. I've tried calling them back, only to get either a hangup or a "Your call is very important to us, Please hold" message (no company name or identification).

Today, however, I got a call from the same number and answered right away, but waited to say anything. After about 10 seconds, I said, "Hello?" and heard someone on the other end of the line faintly say my name. I confirmed it was me, and the woman on the other line identified herself as being with so-and-so company (it was too faint to catch the name) in Utah and Congratulations, I had won money in a sweepstakes. At this point I was so angry that I told her to stop calling and hung up.

This number keeps calling me every week like almost everyday they don't even leave any messages it's starting to piss me off! I wish they would just stop

Just got a call from this number,  person was talking very fast and hard to understand, just said I won something.  He said he was in Utah, but I know he was calling from SD number.  Said he was from a  calling center and didn't know what number they were using.  He wanted to know if I had a major credit card.  It is a scam.

I have been called by this number at least 5 times a day for the past few days.  I have Verizon so I went under my account and put a block on this phone number
