Paymantra — payment doesn't received to the distributor

Address:

Sangli, Maharashtra, 416312

I make payment to my hp gas via (Paymantra) but, my hp gas distributor denied to accept that i made the payment. He says he didn't receive it.
I wait for hours to hours but, no use.
Please give some response. And i am unable to find customer care number of paymantra. Can you send me that number if someone got it. Or tell me the solution. I want my refund
