Called and I didn't answer, no message left. Who would call me from Utah?

Got 5 calls to my cell phone from this number last night.  Answered the first one, a live person asking if I want to take a survey. I said no thank you, I do not want to take 12 minute survey.  

Four more calls followed, robo-calling asking me to go to a website:  www.mwrcenter.com for Mountain West survey something or other, the last one after 10:30 pm. Really annoying.

I got call from this number 5 mins. ago and they wanted to know if I voted Tues. and if I thought Gov. Brown doing good job--then the man with very heavy accent ask if I voted in person or by mail--then ask if I voted for Romney or Obama--when I said Romney he said thank you and hung up...

I get calls from this number several times a day.  No message.  Is there any way to get off their list?

Call telling me there is no problem with my credit card at this time, but that I qualify for a lower interest rate on my card. Tells you to press one to speak to a live operator. I pressed 1 to find out which card this call was about. They told me visa and MasterCard. I told him that was vague, what bank. He listed a few; chase, Bank of America. I told him I didn't bank with any of them, and he hung up immediately. Seems like a scam.
