Byju's — without informing given loan

Sir
My name is pratham gaur. I have purchased a product from you. Your counselor said that within 15 days if your wish to return tab so you can return it. I had send you more than 10 email. But in last email you don't reply us. And without informing us you given us loan. We not need the product so why will pay it. So take it back and refund your loan amount which has withdraw from our account.
