OnePlus India — Refund Not Received

Website:

OnePlus India

On 6th August 2022, I ordered a new "OnePlus 10T 5G" phone under exchange offer. One 11th August 2022, the bluedart delivery person came and rejected the old phone for exchange and canceled the order.
Until today i.e. 22nd August 2022, I have not received my refund amount of 42, 429/- rupees. And, there is no email communication from OnePlus about my refund status.

I have called their customer care multiple times and all of them say that you will get it by tomorrow. But, tomorrow never comes.
