Many thanks @Sybe
I have just returned from 3 hours with yet another IT person. To cut to chase, we have changed the airbnb email contact address, sent a message to the support person asking them to send us a test email and if we don't get any emails from airbnb it will presumably be their issue, not mine. No email has arrived!!! That is another £80 paid out in trying to resolve.
We got email in from airbnb asking us to confirm change in email, which we have done but so worried about guests that are coming in tomorrow. I sent them the key-safe instructions but have had no reply and the whole things just makes it feel so unstable.
I guess as changes only took place two hours ago I should defer gnashing of teeth but as this problem started back on Dec 14th last year I have a right to be v annoyed.
Thanks for tips on hair dye; I shall look into it straight away. Do you have any tips on how to hide from furious guests? Might be needing that one... 🙂
