Stallion Intellectual — Harassment, False Allegations

In September 2017, I got online data filling work from this company. But then this company frauds with me and put a charge of amount 5500 under false allegations. That time I paid the amount since I was scared and not having full knowledge but now again after so many years today this company again contacted me claiming that I have to pay them Rs. 24000 as a penalty amount. However I do have the NOC from them as well. Still they are continuously harassing me under false allegations and giving me unnecessary mental stress. I request to take serious action against this fraud company and now I want my Rs. 5500 back which I have paid in year 2017.
