Axis Bank — credit card emi issue

Address:	Mumbai City, Maharashtra, 400025
Website:	www.axisbank.com/retail/cards/credit-card

I had purchased a mobile from flipkart that cost rs 12999. It was clearly showing me 0 % interest. Emi 1089 per month.
But every month in statement the started charging interest. I complained about it many times. But customer care and their email team did not replied to my issues.
I paid first 3 emi. I warned them please resolve my issue or i will not pay emi. But they did not took my emails and calls seriously. And they told me that they can not do anything noe. This product was having 0% interest bring that proof. By that time this scheme was removed from flipkart.
When i did not pay emi, they called me after 6 months and asking me to pay another rs 15000 after paying rs 3500. They added everything late payment and interest.
I applied for credit card after thier team was continously requesting. Now after selling thier card they forget everything. And try to fool customers.

After 6 months they asked me to pay settlement amount rs 6100. That also i paid. But after so many fights they have still not given me noc for this issue. I told many times that i am ready to pay the amount left after deducting rs6100 and 3 installments from actual amount rs 12999.
To which nodal officer from axis back was ready but after that no body called me regarding that.
I request you to please get me noc for this issue from axis bank. They have spoiled my cibil score.
