Who called from 2017069005

I am so sick of these people calling my cell phone while I'm at work making a real living.
4-5 calls a day, No One there and busy signal when you call back. This must stop

They call me too. No one's there when I answer, but it doesn't hang up the phone either.

I just called it back, and it said "The MagicJack customer you called is unavailable to come to the phone"

They ask who is in charge of office cleaning contract. I just told her we don't use any cleaners.

calls here 3 or 4 times a day. will not answer.  id shows jersey city, nj.
