I boufht a ihone x through capital first, I paid rs29000 as down payment and financed by them was rs 64500, and confirmed me that emi would be 3760.but when i checked my loan detail on App, emi ahowing rs 3924.
Meanwhile i m getting calls from some Indian health organisation and offering some discount coupons, they claim that i have signed the form at the time of taking loan from capital first. The charge of these coupons is approx rs 2500 .
The thing is that niether i signed any form nor i was informed about these coupons.
So i want my extra amount refund.
