Byjus - Byjus app oppose to give refund on an unused product

One of the salespeople from Byjus app had informed us over the phone that he will come for a demo on the product at home. After doing continuous calls we have agreed for the demo. He came to the home and had a demonstration on the product. Informed us that they are giving a trial version to test whether this product is useful or not. He had taken a cheque from us by saying that they need an advance during the trial period. The product reached at home on Feb **th afternoon and my son has viewed the product for *-* days and due to Xth board exam schedule, he did not get the time to review the product and give feedback. He was having an exam on Mar *nd. After that, he had reviewed the product and informed me on March **th the product is not looking feasible for him hence we have informed the seller to take back the product. But they hesitate to take it back and even they have not turned to us for further assistance. At the time of the demo, the seller informed me that if the product is not feasible you can return the product and the amount which I have paid id *****/- will get refunded. He has not informed me of the time period in which I have to return.
We have received a response from the team that you have contacted only on the **th day and it is not refundable and asked to continue the product. I informed the person, Mr Abrar, I don’t require this product but they continuously hesitate to take back the product. These people are cheating customers with false commitments. During the time of the demo, he has taken a cheque from me, if the product is feasible for continuing the product they need an advance. For that, he has taken from me a cheque for EMI process. As I have already informed the team if I don’t want to continue the product they have to discontinue the product with the refund on advance i.e Rs.*****/-. Without my knowledge, they have processed my EMI as well.

I found this is a fraud practice they usually do. Yesterday I found that they have processed EMI and taken **** Rs from my account without my knowledge. Even they have not intimated me that they are going to continue the product and processing my loan. This is illegal and I don’t want to continue this and I need my money back. This is the case of cheating and they are doing this with a false commitment to sell the product. Request you to please do the needful.
