Byju's — Not switching my course to offline Classroom and not canceling online course

I want to tell you that I have purchased Aakash Byju Onlime Course Of JEE On January. After some days I didn't get comfortable while doing online classes so I decided to switch course to Offline Classroom Program.
So I requested them for offline Classroom program.
It's been a 2-3 month but I didn't get any response from them.
It's been 20 days and my online classes also not running, I'm very upset with them.
I only want them to kindly cancel my online course or either switch it to offline Classroom.
