Byju's — Neet preparation course

I purchased a Neet preparation course for my son who is studying 9th grade through a sales person chelladurai who came to my home and gave demo and explanation of the course he forced us to enroll in the course so we took the course by paying Rs 5000/- by initial payment on 25/07/2022 and EMI were arranged for the rest of the amount, EMI deduction started going on still the NEET preparation course for 9th grade is not activated, I contacted the customer care, the customer care executive said that NO neet preparation course is active only acadamic course for 9th and 10 th grade is active, I already purchased two years before when my son was studying 7th std a offline CBSE board academic course( 7th to 10th ) for my son and paid fully. now they are activating the same course which i purchased earlied instead of NEET preparation course, Kindly activate the Aakash byjus Neet foundation course for Grade 9th and 10 else return our money back . registered mobile no [protected]
