Who called from 4153639552

Called the number back.  Recording on a survey about cancer.

Got a call from them at 10:57am, didn't answer.  No message was left

They call your cell phone and business, weekends too. stop it already.

Just received a phone call from CSC 415-363-9552. I am living in Lima, Perû, South America. I found this quite odd. After reading the notes above, I think it was a scam. Thanks.

Hang-up call from this number in a hospital therapy department.  About tired of receiving these types of calls, interrupting work here.  W/ today's technology, can't someone stop this practice?
