MakeMyTrip India — hotel booking cancellation

Hotel is allowing to cancel the booking and giving refund but mmt wants to keep that amount in their wallet and forcing me to use their services again.
If hotel is paying them back, why are they keeping my money in their wallet and not giving refund to my account?

What if i don't have any plans to use mmt services again ever in future?

How can they hold my money which is more than 10, 000?
