The name of the co. is GRANT CLUB GOLD. They are located in Hackensack, NJ. This scam they are running is called a TDOS or telephone denial os service scam. You can read all the details on the FBI website. They call from all over NJ...201 & 609 area codes. Beware...
I keep getting the same thing as well with this number keeps calling but won't leave a message. Have you been getting a call from 201-285-8691? I think its the same people just calling from a different number.
