Bangalore Metropolitan Transport Corporation [BMTC] — charged twice on my credit card for bus pass

Address:

560100

My docket number : BMTCC10232314

The details are in this docket.

Please help., I'm not getting any response from them.

Adding the email I sent to BMTC,

I visited BMTC bus pass counter at majestic bus station on 03/07/2019.
I asked for Vayu vajra bus pass, the person at the counter misunderstood and asked me for gold and swiped my card for Rs.2363
Later when I asked him again he said he said he will cancel the transaction and pulled out the card, but by that time my account got debited for Rs.2363, I showed him the message for which he replied that as he did not receive any receipt from the swiping machine the transaction will be cancelled and my money will get refunded back in 24 hours.

I got the Vayu vajra bus pass for Rs.3570 which was swiped again in my card.
I was not refunded the money for the wrong swipe of RS.2363., I was told that I'd get back the money in sometime. But I waited for nearly 48 hrs and still the money is not refunded.
I've reached to BMTC whatsapp helpline for assistance and they've asked me to write to this email.

I've been emailing them for over a month, they have stopped responding also now.

I don't know whom to reach, kindly help.
