[Resolved]  HDFC Bank — unaccounted emi deduction from credit card

I had made a purchase of rs.21, 240.
When i was billed with the credit card statement i was shocked to see this amount converter to aggregator loan without confirming to me.

The said loan is not at all confirmed with me nor the details are shared with me, i do not want any loan of said format.

I have been deducted emis for the same under "offus emi" without any information.

Aggregator emi - offus (Ref# 09999999980512000029137) 21, 240.00 cr
13/05/2020 offus emi, int nbr:01, [protected] (Ref# 09999999980513005344828) 247.80
13/05/2020 offus emi, procng fee, [protected] (Ref# 09999999980513005344802) 99.00
13/05/2020 offus emi, prin nb:01, [protected] (Ref# 09999999980513005344810)

I wish an explanation and change in the statement generated and a resolution to the quickest.
