RBL Bank — credit card emi pre closing issue

Address:

Kolkata, West Bengal, 700102

I had called rbl bank customer care for emi pre closing purpose[protected] and they raised the request.
I have paid that amount with the pre closer charges and gst
But today i have seen that pree closer charges and gst again deducted from account, i don`t know is this how you guys are supported to the customer.

I just called today and they could not transfer my call to the senior as well as they unable to help me its strange.
Now i realized i did big mistake to take the rbl credit card.
