I was trying to get an upgrade in the United.com. Just under my itinerary in "Request an Upgrade", there is a link: "Purchase a 500 miles Upgrade kit" ($325). After my purchase, I learned that it only works for US, Central America and Canada travels. I will go to South America and would need the Economy Plus Year Plan ($349).
I called United Airlines and United.com costumer services and they didn't allowed me to change the plan or to cancel the first purchase. All the representatives sent me to other sectors or tried to sell the Economy Plus Year Plan (without cancel the first purchase). Several times.
I was tricked by United.com and they didn't help me at all. I am a mileage plus member for years and I am so upset with this situation that I decided not travel United anymore.
The costumer service is disrespectful and useless. They should fire everybody and put a robot repeating: "I am sorry. We can't help you. But before end your call, give me more money".
