Won’t Refund Money

Booked a trip for five lads, accommodation and motorcycle hire for four days paid in full, but due to the present situation regarding coronavirus the airline have advised us that our flights will not happen with the lockdown in Spain etc.
We contacted Redtread re a change of date for this trip or a refund.
They refused this and said they can’t refund monies paid as they are only a small company, Unbelievable!!!
They basically stole our money, beware of them.
