I need to talk to someone about how do I find out what credit card number is being used. second problem is that I was charged on my credit card $14 plus dollars I was waiting at the airport at united and did not know that the waiting area was moved When I got the call I told the driver that it was a 10 minuet walk for me to get to the right area . When I got there he was gone and cancelled me. so why am I being charged.
