Compliance

I don't know if this question is relevant for this forum but if someone can guide me where to log in the complaint, it will be helpful.

We had received a call this morning. The person mentioned that he is from Corel Compliance team and my company has been using pirated version. 

Actually, I have no employees in my company so far.

and I don't use anything beyond MS Office and that also a Licensed Version. 

I don't even know how to use Coreldraw.

So can someone help me how and where I can complain about these people who are calling.
