Razorpay — Refund not issued for excess payment

I ordered a lab test from Tata 1mg on 12 May 2022. At the time of test, I tried to make payment but it failed so I tried again and then it failed again. After 10 minutes I tried the payment and this time the payment was successful. The screenshots of all payments is attached.
The payment IDs of all payments are as under:
(a) pay_JUBV6YlObwkegz
(b) pay_JUBNriHHlGWqdt
(c) pay_JUBPKZhdDva8mI
Later, I received message from Tata 1mg that payment related to ID pay_JUBV6YlObwkegz is successful.
I received the refund for ID pay_JUBPKZhdDva8mI on 16 May 2022. The screenshot of this is attached.
The refund of ID pay_JUBNriHHlGWqdt is still awaited.
I had followed up with the team of Tata 1mg and I have been told that thay have not received any excess payment.
