Croma — Regarding Non Conveyance of information of NO COST EMI for my product and not resolving my problem since last 16 days

I had purchased Ipad on 4 th june 2022 through CROMA online and the mode of payment done by me was through my credit card with NO COST EMI for 6 months offer . In the bill also its clearly mentioned regarding NO COST EMI but till now they have not given any information regarding the same to my bank and the full amount has been cut through my credit card and my bank has told that till Croma doesn't send them the confirmation regarding NO COST EMI they cant do anything. Since 19 th june 2022 I am constantly calling and mailing CROMA regarding the same but they are not paying any heed to it and jus telling me that we have registered your complaint and we will resolve the issue within 24 hrs but till now that is 5 th july 2022 ( 16 days of lodging the complaint and calling them constantly ) they haven't done anything nor have I received any update regarding the same. Who will pay the FINE that is levied on me by my Bank ???? Because of your negligence and irresponsible behaviour I am facing problem since last 16 days but you all are not doing anything except for sending me the same mail again and again that we are working on your issue. WORST EXPERIENCE AND WORST BEHAVIOUR OF CROMA
