My suggestion is that you ask the airline to tell you if they have issued a refund. If they have, then you can start a new discussion with the agency which has nothing to do with dates or time zones They simply need to find and refund your money.
Not important for this discussion, but Chase Travel is now operated by cxLoyalty which is owned by Chase.
United has not issued a refund. The Chase folks said if there's a refund, it'll be from them since they're the one who paid the airline. That's what the Chase rep said to me. It's just that after their "backend investigation", they said I won't get a refund because I didn't "attempt" to cancel, which is definitely false. The date and time was to provide proof that I did cancel and hoping that it would help my case. If I didn't try, I wouldn't have even cancelled it via United. After that call, I reiterated my case, sent them the United time stamp from United(they asked for it) and the sup told me they'll send it back over to them to look over again..... Now I'm just waiting again for a few days now.
