Oh hell, that's terrible for you Judy. You do have a $200 security deposit set, but if the guest disputes any wrong doing here then it may be difficult to claim.
As the Host this is what you should do regarding claiming through the Resolution Centre...
And this is the procedure from the guests side.....
So Judy, follow those guidelines and contact the Resolution centre through your guests reservation confirmation and give it a go.
The other thing is, you do have to spell things out in black and white for guests...they are not familiar with the operation of your equipment like you are and these things will happen. It only needs a small laminated note on the dishwasher..." Please use one supplied detergent table from this pack" , and put the Finish, or what ever you use close handy.
If you do need to contact Airbnb by phone the number in Sydney is 02 8520 3333....Geez I know that number better than I know my own!!!
All the best Judy. cheers.....Rob
