I have purchased a laptop with order id OD[protected] in NOCOST EMI in a credit card. But now i m getting processing fee, high interest on the purchase from credit card bill. Upon contacting customer care nobody is giving proper response. Once they say they have raised a complaint with their backend team and will get back to me within 24-48 hrs but its been more than 2 days that i couldn’t contact with them and hearing the same response and also they are saying i have to contact bank it seems. Bank people saying there is nothing like that, interest will be applied on my purchase.

I have purchased for amount 52867 rupees. And the processing fee from bank is 528 rs. Each emi is of 9250 rs.
Now total its becoming 56123 rupess.

Please find attached invoice, emi and processing fee details
