Byju's — Unilateral Change in Mode of teaching-cancellation delayed

I have registered for online classes (from Class 7th to 9th). During registration I was communicated that I will be given four INTERACTIVE ONLINE CLASSES . Further it was also communicated that each batch will be of maximum size 10 and registered students interested for offline classes will get preference when BYJU's starts the offline class in the city. The online classes started as per commitment for few months but when I changed from ICSE to CBSE I was put in a RECORDED SESSION in a larger batch (25 odd students). These classes were never interactive and when I tried to reach to the customer care they tried convincing me that the classes on ONLINE and this was the only class being offered. SInce I have opted for INTERACTIVE ONLINE CLASSES and the services offered are not matching with what was offered to me at the time of registration, I have asked for refund. As on date I haven't received any information on cancellation from BYJU's.
Request to take-up with BYJUs to process my cancellation request.
