Byjus — Cancellation and refund of live course

I have contacted your helpline multiple times, sent mail regarding this matter but to no avail. My son joined the live classes in January this year and during October one of your counselor contacted me and told me to make a down payment of 10000 rupees and by doing this his grade will be increased till 9th, previously it was till 8th, and I was to pay only the remaining 4 months EMIs. But it seems I was misled and I cannot afford to pay two EMIs for the same course. So I'm pained by this as he is one of your student for the past four years and I want immediate cancellation and refund of my money.
