I was renewing my DSC on emudra on 30/12/2022 when one of there associate Kalpana R. called me & offered me 15% discount to renew it through her link. After renewal they emailed me Invoice which doesnt have GST no on it. I have followed up on her Mobile no, Text message and email. She responded me on email on 3/01/2023 and I confirmed my GST No again but after that no reply is received till today.
