the number keep calling but when you answer it they hang up the phone they call me twice this morning

when you call this number it somehow got forwarded to mine.I had to change my number.I started getting threating calls and I was not the one calling.sorry to all.Trust me it has been nothing but a headache for me too.

They keep calling. I've tried to look them up because they never answer when i call back or when I pick up. But I have no idea where or who it is.

The Number 201-282-6559 is a company called Grant Club Gold.  They are scam artists.  They give you an opportunity to collect  money via government grants.  The catch is, If you pay them $2.97 for the first 10 days, you can access their website to help you find and fill out government grants.  Before your 10 days are up, they charge you a monthly fee of $50.00 a month.  They say you can cancel at anytime but every number and email accounts they give you are invalid.  
The only way to try and get and/or keep your money is to contact your bank and the BBB.

The Number is located somewhere in Cliffside NJ.   The phone is a Sprint phone.
