Who called from 2016215694

I have recived 8 calls from this no. I picked one of them out and it is a company wanting to clean your ducts they just called me thismorning again at 8:14 that is how I found this site cause rogers operator told me to reverse the no. this is really pissing me off due to the fact that I have better things to do then tell these people that I rent leave me alone can someone please help me get rid of these people.

I got at least 7 calls a day from this numbereven on the land line3. czn this be stopped?

I got at least 7 calls a day from this number even on the land line3. can this be stopped?

since i have been on the computer i have had 5 more calls from this number both on cell on land line     how can they be stopped?

like everyone else, i keep getting calls from this number, no answer, etc.

hows is it possible that no one knows who this is? people can hack e-mails, find  ip addresses, but can't find where/what this is? thats ridiculous
