Mytectra Learning Solutions Private Limited - Payment not received as a Trainer

Its a SCAM!!! I conducted a virtual training on behalf of Mytectra Learning Solutions Private Limited for Java/Spring/Microservices course for this institute. First I received a call from them, they told me about a part time trainer opportunity. I took the demo session and then completed the full training. I have given training to * students ****/- Rs. each total of *****/- They promised me after completion of the course I will get my payment in * days. But they never paid it to me. The candidate was very happy with the training and I have proof that he was happy and I completed the training on time. Still they did not release my payment. Every time I call they give me a new date but never pay me MY MONEY. Every time they say they need to take approval from their CEO. I called their CEO Mr. Venkat multiple time but he is not receiving my call also. They are running a SCAM on the name of online/virtual training. I have all the proofs that I completed the training.
