Pending Cashback/Rewards is cashback money on the way.
When we have tracked your transactions via CouponDunia we add the cashback to your account as "Pending Cashback". As your purchase is still awaiting merchant confirmation, subject to no return or cancellation and other terms, we cannot allow you to withdraw this amount and label it as "Pending". In 4-8 weeks, this amount should get updated to confirmed once the merchant approves the purchase.
