Byju's — Refund for student Nisaanth

Hi, I am the parent of student Nisaanth. Still now your senior manager hasn't contacted us and EMI's are debiting from my account.I have done with every formality I have canceled within 15 days trial period. I have returned the product. I also sent all the proof but still my money is not yet refunded. I don't know why my request is in progress. I have done everything correctly as mentioned but still, my money wasn't refunded instead of that you are taking my money as EMI. What type of logic is this?. First of all, cancel the loan it was irritating even I had returned your product but you are taking the loan amount. Is this fair? .whenever I mail to your team the reply was our senior manager will contact you, but still, now he/she hasn't contacted me. Please take this as seriously and reply ASAP. In this mail I have attached all the proof once again please verify and refund my money. The total refundable amount is 9119 INR.I canceled the product on the 6th of May and returned the product on June 7 but still now our money has not been refunded.
