Freecharge Payment Technologies / Freecharge.in — Paylater dispute

Why is my paylater due is higher than the total amount of transactions I've done? Also none of refunds i got was settled in my total amount due and even without those refunds being deducted from the due it's still higher than the total amount of transactions I've done i want answers, transactions done from 7 August(last bill paid on 5th August) is 102+97+70+209+276=754 and my bill is 852rs out of which 102+70 should be refunded so bill should be 582??? so can I consider this as some kind of masking by the company and except a proper reply for this fraudulent billing? If i didn't notice i would have ended up paying all the extra amount of money and maybe would have done the same in future and past bills i want a proper compensation for this with a proper response
