Orbitz Plant Pop-Up Hotel

Do I have to print out my itinerary or can i just show my phone at the ticket counter

It is 1:38 PM on March 12/2022 and I am trying to cancel or change my flight tonight to Europe on Finnair.
All your customer service lines are busy and then dump me and there is no other way to contact Orbitz. The chat just gives me the same phone numbers. I am doing what I can at my end but you are not letting me cancel or change. This is on you - not me. Woodland Hills California.
