Who called from 2103315800

I recevied a call also; two in fact without a message.  Finally on the third call I answered.  It was a customer service rep for the Rio/Paris hotel casino (Harrah's).  I had an issue with reward points/reservations and they were calling back to resolve.

called me. claimed they were at&t and said that my phone number showed up on a barbara (didn't really hear the last name) phone bill. i said i didn't know who that was and then she apologized and hung up.

I got a call from this number, no voice mail left....

This number called me 5 times never left messages. I figured it was not important otherwise......What do they want anyway?

Today, received three calls, no message left. Now that I have read this interesting post I will BLOCK them.  Thanks for this info!
