So I booked an international round-trip through Chase UR and needed to cancel the trip. I tried calling United 1K line and have them "take over" the ticket (and would happily pay $50 fee to do so) so that it would be a travel credit in my United.com account, but 1K agent said it is not possible. 1K agent also tried a dummy booking to see if she could take over the ticket instead of crediting the ticket and was unable to as well.

Chase UR website is not letting me make any changes to destination city, change to one-way, etc.

Any other tricks to get the credit into United.com? I feel like I'm going to be forfeiting $1500 because Chase UR online or via phone are unable to help either.
