I had purchased 01 no. 1plus 5 mobile handset online 12th aug2017, for rs. 27, 724/- by exchaging my moto g phone, and at the same time i had opted for emi scheme. But you have charged full amount of rs. 27, 724/- and charged the emi amount of rs.3, 575/- also. So kindly arrange reverse the either the full payment or emi amount.

Revert me back immediately on this matter very urgent.
