I appear to have been overcharged per night for an upcoming rental (advertised at 86/night, however the receipt shows 97.91/night), but the chat function is useless. Once I got through the bot, the community expert didn't know which reservation I was discussing. (Only two choices so really not that hard - the one at 97.91/night, right?.) Tried again next day (also left the confirmation code) and several hours later heard a reply, but, as I was no longer active, so that community expert left a message. Very frustrating. Any ideas?
