Hi @Kelly126,
That is strange that you cannot see your upcoming reservations. You should have received the details of your booking in your email - was this not the case? I can see that you posted this on Friday. Did you manage to contact your host? Are you still unable to see your future reservations?
If you are still looking to contact Airbnb, this Community Help Guide gives advice on different ways to contact them. You could try the US number or Twitter/Facebook, as there is no number in Nicaragua.
I have moved your post here to the English-speaking Community Center, please let me know if you want to change the title!
