(877) 275-6835

I have received dozens of calls from this number. The person (or computer) hangs up as soon as I answer the phone. I called it back and it said it was the American Institute for Cancer Research. Unfortunately, the phone message didn't provide an option for having my phone number removed.

I called the number back and heard an automated voice say that it was the American Institute for Cancer Research

Caller hung up at once after I responded. I have no idea who this person is or how they obtained my cell phone number.
