It's called 'LipoSlim' and it is a total scam. You should be able to program your phone to block this number > 201-574-1010 I just did that. I am in British Columbia.
I received a call from 2015741010 on April 21 asking for my wife. A man's voice was on the other end. When I asked who was calling her, he said he was from lipo...... When I told him whether he has any message as my wife was not in, he said he will call some other time and hung up. I live in Manitoba and the call seem strange to me.
