Without knowing more facts, it is hard to be specific. If they are telling you that you must change your corporate name, that is not likely the cases if you have prior use. If they are telling you that you can't use the mark in some other way, there are additional facts that would need to be asked. I strongly urge you to get specific legal advice based on your specific facts. You may also be entitled to interfere with any trademark registration process if you have the right facts.
This should not be considered legal advice and is provided for general education only.
