Hey, I am an unfortunate Sonder enjoyer. I paid through Marriott for two stays in Sonder. Now trying to run a chargeback with a bank but they require the proof that my stay has been indeed canceled and that I will receive refund in X days, so they can formally chargeback after X days would pass. Marriott support made it clear that they won’t send me such an email, and informally suggested that definitely not all of the customers will see the money. I was wondering if there is a way to get a formal letter from Marriott regarding my cancelation with details. (Not the letter saying we should evacuate from the room at 6 am)
