Air India — booking denied money deducted

I made a booking of air India flight on 25th April for flight AI993 from Bangalore to Dubai on 7th on May 7 but after the transaction succeeded, there was no booking confirmation. I called up air India n then asked that the booking got cancelled from their end and I need to send mail to [protected]@airindia.in to process refund and I need to initiate another transaction to make booking. I made booking again and money got deducted again but the previous deducted amnt was not credited at all. The customer support has no decency or watsoever to reply back to the mail I sent atleast confirming that they will act on it even after sendin several mail's. For some problem at their end we have to suffer n perform so many follows ups calls but nothing s being responded forget amount being credited
