I'm having an issue with United on refunding a Trip Protector charge for my flights in June. It seems that United.com passed to Allianz that I want the Trip Protector (travel insurance) for this ticket. I have the screen capture that I took where I did not select Yes, but also didn't select No - So no choice was made.

I've submitted a refund request thru United.com Refunds link with the screen captures and fare basis. They requested a copy of my Credit Card Statement with the charges and today stated I should Dispute the charge with my credit card company. Which I have as of today.

As I pointed out to United (in 30 years of flying them) I've never bought travel insurance for flights (especially Business Travel).

My questions
1) Should I press further with United.com since it really seems like their website made a mistake passing along the "request for insurance" or,
2) Should I just continue along the lines of the Chase Credit Card dispute?
