Did not leave message and when I called back it had a recording that the number was not in service.

Didn't leave me a message, either. I called back 3x and got a busy signal each time.

I received a phone call from this number asking if I would think about a one-time contribution to a breast cancer program. I was not told what company they were calling from. When I replied that I might consider the contribution, but would need more information to probe for answers, the lady responded that I could only be sent information if I committed to a contribution. When I told her that I was not interested she hung up on me.

Just got a call from an older lady maybe 50s asking for Jon. I said I was not Jon and she responded Ok we will try later. Before I could respond she hung up.

Got a call from this number, not sure if they said the company name, but they were probing for donations. When I told her I wanted to remain anonymous and not give my address out, the conversation pretty much ended. Weird.
