PhonePe — not refunding the amount for the failed transaction at gateway

I did a transaction (P2006131147181949526646) to jsp honda merchant, while i was doing the transaction i received 'gateway error'

So i did once again, the transaction was successful 2nd time

But amount has been deducted twice

I contacted the merchant and got the update amount isn't credited in the merchant's bank

I would like to know where was the amount of rs. 393?

It's neither with phonepe nor jsp honda

Can you please check and initiate the refund immediately
