Non-existant customer service.
Absolutely useless customer service. They keep passing the issue to a different person, up to six now, and not one of them reads or understands the issue, not to mention the contradictory responses. Requests for escalation to a manger are just ignored and it is clear that there is no interest in helping or doing anything other than taking your money. I would very strongly suggest not booking with Sonder or Marriott Bonvoy.
