If you are in US it is actually illegal to remove “stuff” if you have paid for it. You may point out to your old dealer that you can sue for all the money paid to him unless he restores the system. Then after he restores the system that, you can change the dealer of record in the C4 site, and revoke his access, so he cannot access your site again. The reason for that is if he truly removed all drivers and connections (as opposed to programming), a remote dealer cannot program your system because they do not know what you have (lights, etc) . You would need a local dealer to do that. So getting the old dealer to restore the system is faster and easier. Then a remote dealer can do the rest in terms of the programming you want. I would also have new dealer change the director password so old dealer has no way to get in. Be careful though since the old dealer can password protect the director to make it hard for new dealer. Composer HE won’t help you since you need Pro to do any real programming. If you have a backup of your system there are ways to upload into director to make this much easier. Sorry this happened. I have gone through 4 dealers locally (two are in jail, one in drug rehab, one never answers calls). It is crazy how C4 let’s anyone be a dealer. Find a good remote dealer and you will be happier.
