Byju's — Cancel enrollment refund full amount

So far, I have very worst experience with the BYJUS Grievance Team. Though I have paid through EMI Option for Rs.80000 and the invoice clearly says the payment is 80000, still the BYJUS team is telling they can refund only Rs.73k. This is totally unacceptable.

Please address this promptly, cancel the enrollment, collect/pickup the materials and refund me the full 80k. I will take care of settling my EMI accordingly.
