Hello Daniel

My cell number belonged to a "Daniel" before I received the digits last December. Not only does it show up as Daniel when I call someone, but I get people looking for him all the time. And today, I received an "Easy Update" from United stating that Daniel was flying from Austin to San Francisco, March 19th, on flight 657, estimated to arrive at 8:17 a.m. at gate 69. I suppose I should call AT & T to ensure they make the change. But how can I let Daniel go?
