Have not received any course material or link for course which I purchased on 29th July 2023 after paying 1st installment of Rs 7198 . Jatan and team asking for 2nd payment without and course Material. If I am not going to pay 2nd installment 1st won't be refunded . Jatan and team are fraud no teaching just he is asking all to pay full amount for access to course link and no one even responding on phone, whatsapp or mail from his end .
