The host is saying that since a contract once existed that it is now a civil matter and they don't have to take down the images. They might be right, I haven't heard of this before.
I think what they are telling you is that it is a contract law matter, and not just a copyright matter anymore.
The other party has a contract that gives them the rights to display the content. You have terminated the contract, but the host is not a court so they are in no position to judge. They can argue that it was improperly terminated.
So that contract takes it outside the realm of simple copyright infringement that the DMCA was put in place to prevent.
Talk to a contract/IP lawyer.
