Mobile E Mart — Frauding with me about delivery and refund my payment

This company called me and wanted to know my debit card number after seeing my previous complain about not giving delivery still paying Rupees 424 by prepaid. I paid them through net banking paytm and they can easily refund my money through my account number and bank Ifsc code. But why they wanted to know my debit card number i don't know and i disagreed to share it with them then they said they can't refund me without my debit card number. So it is certain that Mobile E Mart is a totally fraud company. 1st they takes order only with prepaid and gives expected delivery date then they don't give delivery, then if anybody complains then they call that customer and wants to know his/ her debit card number. I think this is totally fake process to deal with customers. So kindly refund me through my account number and ifsc code else i am ready to take all other necessary steps.
