TPSL — Booked business lounge at IGI airport

I booked a place in the international terminal lounge at Indira Ghandi International Airport for 2 hours, I used online bank transaction method to pay for the fee, ICICI bank went through with the bank transaction only to be greeted with a page stating.
"payment gateway error- This error has occurred for one of the following reasons : Merchant configuration issue. TPPGE004"
The money has gone through and has not been refunded, I have had no email showing that my booking was successful,
help would be greatly appreciated, thanks.
