Spice Jet Airlines — my money got deducted but ticket didn't get booked

Address:

Pune, Maharashtra

I was booking my ticket on July 8th 2019 from pune to Dubai amd once the paymetn was complete the page showed some error and no ticket was issued. I paid an amount of 16, 866/- amd it was a return flight as well international fares. It is quiet high of an amount kindly look into it. My email id is [protected]@gmail.com. I booked through debit card of hdfc bank and I have no ticket and my money were also deducted. The airline told the money would reflect in 48 hours but it hasn't yet. I have lost my money and have no ticket either. It is a large amount that i expect to be refunded. The bank was not reachable on this issue and no ome has answer to this problem i am facing.
