Indian Bank — Indian Bank - Pos/Ecom Transaction using debit card. Transaction failed but amount was debited

I ordered a foam matress worth rupees 9637 from flipkart i paid for it in advance through my rupay debit card was deducted from my account but it said order not placed as payment wasn't confirmed by the bank on 14th feb at 1.47 pm. They said it was an issue from the bank's side and money will be credited back in your account but it's been a day and it hasn't been done. Shall be glad if you could intervene and get refund of rs.9637/- from indian bank. While trying to lodge a complaint in the bank's customer redressal system, a pop exhibits that no failed transaction on that date and doesn't accepts the complaint.
