Byju's — Course Cancellation & refund

We have made the registration on 13th March 2022 and started to attend the classes from 21st (monday) to 30th march Wednesday attended only 7 byjus classes. On 4th April we have mailed to cancel the registration and not able to attend the class it came as expired subscription. And there is no response from byju's team so i have mailed the details again on 6th April to support & Cancellation team. And still date i have not received any feedback. i called the support team first they informed me that the issue has been escalated after constant follow up they are informing me that the process cannot me cancelled after 15 days. if they are dragging me like this my due date for payment will come, I have raised a complaint in the Byju's complaints resolution site also but i have not received any ticket number yet. Though i have done all this till date i am receiving the messages to attend the class . kindly request your support to cancel the course and refund the amount.
