[Resolved]  Air India — no refund or any info regarding its status

I tried booking ticket from chennai to port blair on 21 dec 2019 and return ticket also for four people. But due to some technical issues my money was deducted from my bank account but ticket was not booked. I called the customer care and they told to send an email to [protected]@airindia.in with booking details which i propmtly did but even after 15 working days there is no refurnd nor is there any information regarding the refund status.
Please look into the matter immediately
