Byju's — I am complaining about money refund process

At the time of admission counseling, it was said by Byju After taking the admission, the kit will be delivered and after that we will get 15 days for the trial. And if we don't find the method right in 15 days of trial then we can apply for cancellation and will get full amount refund. But when we did this, we are troubled for almost 10 days and no one is even ready to listen to us.
By giving new clauses, efforts are being made to mislead us into different things instead of completing the cancellation process.

We are very upset, so please help us by solving our complaints as soon as possible.
