[Resolved]  Lenskart — "product stocked out" after order confirmation and payment

The same issue has been put up before too. However, the resolutions are blurry hence here i am. Firstly, after using store credits, the customer care calls me up to make a fresh order since they couldn't work out their store credit system. Which i denied because it was the second time they were asking about the refund and cancellation issue. However the person agreed and confirmed my address details.
4 hours later, when i check the order trackings in the app, the product is 'stocked out'. Can you look into this matter? And clarify the phase which came after all the major procedures of payment and prescription.
