calling not sure what regarding.  Will not leave message

called yesterday and today.  No caller when answered, no message when left unanswered.

getting call from this number everyday since last 2 weeks. Nobody says any thing and leaves no message if call is unanswerred

Received several calls from this number over the past few weeks.  The last time I asked who was calling and he gave name of Nolan something.  He asked for one of our employees by name and when I asked what company he said Courtesy Health Care. When I asked him the nature of the call he said he was calling on behalf of a Wheelchair charity. I believe they are a telemarketing group for different charities. I just put him on hold and continued to work and he held for a while so I finally cut him off. I tried calling the number back it just rang until it disconnected.
