Hi @Harjeet1,
you should have been paid the rent a day after check-in, plus bank delays.
Did you specify a payout method in your profile? Did you check this method?
I had a look on your listing and the electricity bill is not mentioned in your listing, so I guess you will not get that money.
To claim any extra fees, they need to be indicated in the listing. The guest needs to be aware of the fees before he books, otherwise you cannot claim that money.
A few general thoughts: your villa costs the same for a single traveller and a large group. You should add extra person fees, maybe after the second person. If a couple comes alone, it's less expensive and if there are more people, who use more electricity and water, the 3rd, 4th etc person pays their share.
It's theoretically possible to ask the charges seperately, but you would have to indicate that you will check the electricity meter and water counter etc with the guest at check-in and check-out and then they will pay xx / kwh, yy per m3 water etc. That's complicated, therefore most hosts just add an average consomption to the price and extra person fee.
Type "contact airbnb" in the search field on the community center, there are some collections of numbers. Easiest is always to call or chat. Or twitter/
