Spice Jet Airlines — spice jet airlines - no pnr or ticket issued though the amount was deducted

I booked a flight for 6:10 am on 21st april, 2019 from hyderabad to mangalore via bangalore. I payed rs.9, 046 for 2 passengers through netbanking from hdfc bank. The transaction got processed and i received the confirmation message from my bank about the transfer of money. However, i didn't receive any booking confirmation or booking number or e-ticket from the airlines.

I waited for a couple of hours and tried contacting their customer service, i was made to wait for a long time, yet call wasn’t attended. I mailed their customer service id, there is no reply for my e-mail even after 24 hrs.

I called the customer care today again but the same issue, no one attends the call, only the voice over saying ‘all customer care executives are busy’ gets played.

This doesn't seemed to be an isolated instance. I saw few other customers complaining of the same issue.
