One conversation:

Me: "Hello, I'd like to ask why all the loyalty points from my MILES card is gone."

CS: "Sir, it says here that you upgraded your MILES card to a SMILES card. If you did not request a points transfer, they are gone."

Me: "Okay, how do I do that?"

CS: audible eyerolling "You should have done that while applying for an upgrade."

Me: "You can verify my details for both, right? Can't you transfer the points over?"

CS: "Ugh." Hangs up
