Who called from 2675194002

Saw twice on caller ID yesterday and today. Caller left no message. Called the number back twice and operator said call can not be completed. I believe area code 267 is a Philadelphia cell number.

It is the number for the American Red Cross

The lady requested two minutes of my time to answer some questions concerning a survey of radio stations I listen to.

I did not answer. ID came up only as Philadelphia.

Have received 4 calls from this number, with no one on other end.  When you try to call it, operator says call cannot be completed as dialed
