Corporation Bank — void sale transaction value not received till date

Address:

New Delhi, Delhi, 110089

I have done a payment of 1100 inr on 18 aug 2018 using my debit card number [protected] to purchase an item from a shop (Image 1) for which the amount 1100 was deducted from my account. The shop vendor cancelled the previous transaction immediately (Image2) but the amount was not credited back and he again did the same transaction of 1100 (Image 3) and told us to wait for 1-2 days for the void - sale amount to be credited back.

I have waited more than 12 days also mailed to corporation bank but no response and still the amount is not credited back. Kindly help me in getting the refund for wrong transaction of amount 1100 in my account urgently. I have attached all the images of the transaction slips.

Kindly find my details below:
