Byju's — non delivery of product and no response after payment

My name is sunil kumar d, mob no [protected]. I had enquired for byju's learning app for my ward ashvath divakar for 4th standard. Accordingly, rep of byju's app, mr. Mayank joshi, visited my home on 02 jun 19 for enrolling my ward in byju's learning app. He made me to transfer rs 7125 to his company and ensured delivery of the product post clearance of emi procedure for balance amount around rs 40000. The emi initiation was cleared by 05 jun 19 after a verification call from them. Since then there is no response and the rep is also not responding to my call.
