Who called from 4697186655

They've called several times this past week. I only answered once, which was yesterday. I said Hello and there was silence so I hung up.

The phone number is 469-718-6655.

What is this all about?

Got a call, last of many, from this number.  Let my answering machine take it.  No message; just a dial tone.

The caller rang twice, then hung up before I could even see who it was.

I called the number back, it leads to a recording saying Thank you for calling the Breast Cancer Prevention site.

Call daily no message, I do not answer
