Dunkin 10 Dollar Membership Benefit

I missed out on todays Dunkin 10 dollar Reward. I kept getting the error message: A rendering error occurred: Cannot read properties of null (reading 'fields') and the screen was blank after the text.

I logged in to the app. and tried 2 computers and 3 different browsers. I tried on Chrome and Firefox and got the same error. I was not able to get any of my diamond member benefits today. I talked to someone at chat and they were not able to help. They said they can't add the reward to my account. I left a 0 score for the chat and got a call from someone just so they could transfer me to a business account department. I don't have a business account. The rep at the business account did not understand my problem. Then they transferred me again and the new rep did not understand my issue. After a while I think they just hung up on me. All I wanted to do was report a system error that was not letting me get my benefits but nobody can understand that or have a way to submit a ticket for me. They can't even add my benefit on request. Very frustrating.
