Indigo Airlines — Charged thrice and Refund not given for more than 2 months

Address: Chennai, Tamil Nadu, 600076

I was traveling from Delhi to Chennai on 11th Dec'16, PNR--(KIKLYR)
I was carrying some extra luggage for which i was supposed to pay 11, 000 INR.
The person at the payment counter swiped my card, i entered my pin and she told me the payment has not gone through, so she swiped my card again and I entered my pin and she told me that the payment has not gone through again.
So, i tried paying using a different card of my husband and the payment went through.
However, after looking at the messages from my bank, INDIGO has received all the three payments of 11000 each which is 33000.

the transaction ID's are as follows:

All these three transactions were made on 11th Dec'16 from POS--02PL[protected].
I have attached my bank passbook photo & my credit card statement which says the payments have been received and no refunds have been made
I would request you to kindly help me with this
