Who called from 9015621604

I got a few calls from this #. Did a search on ST. Jude and found this site http://www.stjude.org/ - they say it's pediatric treatment and research facility. Is this the caller? Did anyone else get the calls?

I got calls from that number a couple times this week. They didn't leave a message.

The same # called my house too.  Once when it was picked up they said something that was not clear.  St. Judge was the name also.  who are these people?

Sorry, misspelled st. judge before.  Does anyone who these guys are and why they call?

No one answered, later it hung up. This happened a few times before.
