LittleApp — payment successful but order not generated.

Made an order of Rs.3325 to an Restaurant using the little app, money got deducted but the Order is not generated. Contacted the payment gateway and the transaction is successful from their end . Unable to contact anyone from the little app as their customer care number seem to not found anywhere in the app . Have raised a couple of complaints but no one has gotten back . Starting to feel little app is a scam .
