Sony India — SonyLiv subscription

I paid for the annual subscription of Rs. 999 on SonyLiv app on 7th Jan 2021, but my service wasn't activated, after waiting for some time I paid the same amount again and this time my subscription got activated. So in total I paid Rs. 1998 for a subscription that was at Rs. 999. I contacted SonyLiv throufh email subscription and Twitter, they hardly replied, they asked for transaction ID of my payments, which I shared, after 2 days they said my bank rejected the first payment. So I checked with my Bank, they confirmed that the money was paid twice to Sony Liv, today after 5 days SonyLiv support has stopped replying to my messages, please help as I have been cheated and robbed.
