Dineout — Made wrong transaction through dineout app

I have made two bookings from my dine out app one is bbq nation and the second one is exotica, due to some change in plan we didn't went to exotica and had buffet at bbq nation while making payment i have made payment to exotica instead of bbq nation. I have already raised a ticket about the issue and also got ticket I'd: 571251. It's about 10 days since I raised the ticket till now there is no response from dine out. This is the worst experience i ever had.
