Byju's — Unethical Behaviour during home visit session

I had given a scholarship test for UPSC on Byju's for which a person (Abhinav) visited my house. He took 2 hrs session regarding the preparation and asked tough questions. I refused for the scholarship. 2 days later a person again called up regarding the same saying that he heard the recorded session at my house. This was a total breach of my privacy as I was not asked or informed anything about the session being recorded. He also talked rudely saying that don't give the exam. Very unprofessional and Unethical behaviour.
