Can I take refused freight to a storage facility without consequence

I delivered a load to point a to b on time but some of the load was refused due to the way it was processed from the shipper.Because i now cant get this load off my next load defaulted. I was asked by the broker to take it to a storage facility but we are not agreeing on a price. I fill i need compensation for the load i missed.

What are my rights,this broker is very nasty even though i have his freight. Can i just dump it.
