Reliance Money — EMI debited two times

I got an SMS from reliance money on my mobile regarding the payment of my overdue EMI on the 14th dec 2021, I went through that link and made the payment through Paymino which was successful.
On 15th dec 2021, the EMI amount again got deducted from my account.
I complained about it on there customer care number, there representatives assured me resolution but no no action taken.
I wrote an Email to there concerned team and got an automated response but no action taken. Now it's more than 48 hour of the complaint but still no action has been taken.
Please help me getting back my money
