Since when does a colleague qualify to be a person's supervisor. Give us a break!
Code-sharing confusion scuttles Bahamas vacation:
"When you're on a code-sharing flight, it means you need to be extra careful. Don't just call your airline to confirm the flight - call the airline operating the flight. A system error like this, while rare, might be caught with a simple call.
If you're stuck in a situation like this again, politely ask the Expedia representative to escalate the call. You can do that by calmly asking to speak with that person's direct supervisor - not "a supervisor" or "someone in charge" since that can be interpreted in many ways and could land you with an agent's colleague who will proceed to tell you it can't be done."
