Canara Bank — Money not reflected in account

Address:

Karnal, Haryana, 132001

I cancelled the product from the Amazon and amazon refund the money through same source i.e debit card of Canara bank.
The refund of 1749 rs. has been initiated by Amazon and for the same they provide the reference number 7522608270160113417433633.

I talked with customer care of Canara bank but they are like, they dont know anything about this, and was saying go to the branch or call to customer complaint number then I called on customer complaint number, they also didnt provide me any solution.
