I have paid an amount Rs.*****/-. At the time of payment it was informed to by Toppr executive that you pay full amount Rs.*****/- and later you can convert this amount into EMI and Toppr will pay the extra amount over and above Rs.*****/-. Total amount i had paid including interest Rs.*****/-

It was also told to me that a mentor will be provided for the student who will provide a time table and help the student in case of any difficulty. But not such service provided by Toppr. Since last year I am asing for refund but they are not reponding my mails and calls. I want my amount to be refund. Anuj
