Canara Bank — debit card dispute regarding payment

Address:

21/2, Gariahat road, Kolkata, West Bengal, 700019

We made a purchase of rs. 11, 200 from a shop. There were total of three debits of the same amount, whereas one was reversed. The remaining amount of rs. 11, 200 is still untraceable, since the shop has received only one payment. Their bank also has no clue about the same. Where is my money and why was it debited thrice? The dispute is regarding an amount of rs. 11, 200 which is untraceable right now. The payment was made on 30th august 2019 at new geetanjali creations at gariahat.
