Aljandre - Did you eventually get paid? How long did it take, if so?
I'm having the same issue... last week I extended a guest stay for 4 additional days, I was paid for the initial 2 day stay but not the additional 4 days because Airbnb was having trouble collecting that money from the guest. I'm not sure why Airbnb would allow the guest to extend their stay before confirming payment!
It's been a week now since I was suppose to get paid. I'm really angry because the guest was fine the first couple of day but then became the worst guest I ever had stay by breaking all my house rules which included no parties and no smoking. The last night of their stay I was awaken by the smell of weed and the police was out front of my house. When I went to write a negative review, the guest was no longer active. It's very frustrating to deal with horrible guest and not get paid.
Airbnb makes 4 billion in revenues and can't pay $400 for a service that was rendered by a superhost! I will no longer extend anyone's current reservation because I'm not confident I will be paid in a timely manner, if at all. I would suggest everyone to not alter reservation, just create a new one.
