I Just got a call from this number I had a call yesterday as well.Its music at first then the first time was a guy asking if i was there by my first name, Then today a woman asking for me by my first name!
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.
