LittleApp — refund from little internet pvt ltd

I had purchased a voucher from little internet pvt ltd for salon services in dazzle beauty salon. When i went to the salon to redeem the coupon, i was informed that the parlour is no longer associated with little internet pvt ltd. I even tried to get back the refund but that was in vain. Even the customer care number is not working. When should i expect to receive my refund?
