I want to surrender/cancel my subscription of tablet learning program (ICSE 9-10 and 8-10).please collect back your tablet .while using your product I realised it was not completing my objective and I am not able to understand anything through it.therefore now I have to opt for coaching classes and this product is completely waste of time. And if I do not understand why I will pay the money.
Please collect your product .Also discontinue the deduction of ECS from my bank account
