US visa fees

[Armanii]

Paid fees in last Dec for both h1b and h4

did not book slot as did not get one 

employer allows to travel if we get slot - slots are not released in well advance 

I think fees are valid for 365 days
 

Will they refund if slot not booked ?

or 

will they give extension?

I think no extension expires after 1 yr or 3 reschedules
