Think & Learn / Byju's — to cancel byju's ias course

The course is not like that the client said to me.
I have paid amount of rupees 5200. I have get tablet before 10 days so kindly cancel my order. First they said me that in 52000 they will guide you till you get qualify for ias exam and now they are saying it's only for one year. And after one year you have to pay half amount to continue the course. If byju's did not cancel my order i will not pay next amount.
