This number keeps calling me and when I called it back it put me on hold for 4 minutes before I hung up.

Call came in to my cell phone various times during the day.  When answered, the party asked for someone else [my sister] and I told the person they had a wrong number.  I was then grilled by the caller as to who I was, did I know the party they were looking for and could I take a message for that person.  Very rude and never identified who they were or where they were calling from.

Keep getting numerous phone calls to my cell from this number....how do i get it to stop?  they never leave messages

I just got a call tonight from this number. They also did not leave a message.

They kept calling me and not leaving a message or I only got patial messages but not saying for who.  I did a rvese search and paid for it and it told me that this is
R.A.I. CREDIT CORPORATION
New Brunswick, NJ 08901

If anyone knows who they work for that would be great.
