Canara Bank — I'm complaining regarding Refund of money and poor administration in the local branch

Respected Sir/Mam,
I deposited an amount of Rs.1000 (500×2)in my local Branch (Periyakulam)of the prestigious bank(Canara), but due to issues with the machine my money got deposited but wasn't credited on my account. Hence I wrote a letter to the branch manager regarding the issue twice, but there was no positive response from the bank, it has been more than 20 days from the date of submission of my letter with reciept attached. So please help me get my money back.
Thank you.
I am attaching the receipt for your kind notice.
