How to cancel a trade license after business failure

I hold a professional trade license with a 15% local partner. However, I have closed the company in early 2019 and have not renewed the trade license for the past two years.

The business was not good and hence I did not pay the sponsor fees for two and a half years. I want to close the company officially and also cancel all the visas linked to the company.

The local sponsor is not cooperating and he is asking for the past three years' sponsor fees, which I don't have. Please guide me on how to cancel and return to India without any legal hassle with the local sponsor.

Please advise!
