Complaint Review: United Airlines

Thanks United, all I have done is be a loyal customer for over 10 years with almost all of my business and personal travel. They offered me an upgrade, i paid for it, recieved confirmation and then they decided not to honor it. In fact, they tried to triple the price. Tammy Duarte, supervisor was rude to me and said that she/they are unable to honor what they sold to me becuase she cannot manipulate pricing. That is comical becuase this is exactly what they did to me. I think it is time i give American Airlines or Southwest a chance to earn my business.
