Jumbo jobs hyderabad - Refusal of refund

My husband and I had been browsing for job opportunities in Qatar. My husband got a call from Mr. Akshay from Jumbo jobs regarding job opportunities in Qatar. We were not convinced, but he assured us, saying that the amount would be refunded when we'll lose interest, or when they'll fail to provide job opportunities. I made the payment. They sent us an email regarding a single opportunity each, in Qatar. After that, they did not bother following up. We had to repeatedly call them. We were assigned a certain Nagalakshmi, whose work timings began at *.** PM. she was on leave for most of the days and did not respond well. We had to call them repeatedly. All the attempts from their side were half-hearted. They sent us one more opportunity after many days. I did not follow up as expected. We got tired of it and asked for a refund. They declined. We initially gave a personal reason, anticipating acceptance. They declined repeatedly.
