Byjus — No refund received for booking amount

I was reached out by Byjus team regarding their Early learn program on 25th April 2022. A consellor came home and tried to convince reagarding the subscription and as I was not sure hence I asked them to take sometime and they suggetsed to to pay a booking amount of 3000
and take a decision in a week. I took one day to decide and immediately called them the next day on 26th April to not continue with the subscription and asked them to refund the booking amount.
The councellor asked me to send and email to their support team. I emailed them a written request to Byjus Support, Team BYJU'S and the counsellor avesh nigam on 30th April.No body is responding to the email and refund is still pending.
