I'm getting calls. Did not answer

I've gotten calls the past couple of days from this number. They don't leave a message. If I don't answer the first time they'll call a 2nd time right after the first call. The same thing will happen the next day. The call is coming from Utah. I know it's not a bill collector because I pay my bills on time. It has to be a telemarketer

Missed a call yesterday and today from this number no message left on my voicemail.

the company is TNS global.  its a market research firm the number they're calling from doesn't get you anywhere, i recommend answering and asking they "scrub my name from the list"

Just received a call from this number. No message was left.
