It is a telephone call originated from Schering-Plough.  More than likely Schering-Plough's Global Medical Information Group located in New Jersey.

Called 11 times to my husbands cell phone. I called back 3 times and they said Sharing _____ system. I could not understand the second word.

I called them and got a rep and everytime they say ignore the call they are having phone problems.

I know we don't owe anyone any money and my husband has had this number for at least 2 years now.

I can't imagine how phone problems would randomally select my husbands cell phone and call it over & over. That makes no sense!
