Byju's — Language problem in premium course

Address:

Basti ,Uttar Pradesh

I have taken a course of three years 10th, 11th and 12th from byju's For fee of rs. 75000. which is taken by me in 1 year only.
Now i completed my 10th class form Byju's tablet and it was fine because your course was in both the languages.

But when i started 11th class, i find that videos are in English audio only.
Which is very very hard to understand for me i am living in a vilage where no English tutor even in school no english is read.

So this course is useless for me if it not in hindi you should told me earlier, but you have taken the full fee in 1 year only.
I don't have enough money to buy another course.
So please help me. I request you
Please make my videos in hindi or return my 11 & 12th fee so that i can buy another course from any other company which is in hindi.
This is very imp. Time i have to do good in my exams in 12th boards and jee mains.
If you not help me my future will be wasted.
Please refund my fee or change my language.
