Airtel — DSA Person from Airtel Cheated me

One Mr.Dhaval Prajapti's oofice approached me for the Airtel connection, i gave consent that i would like to port my existing number to Airtel.
Then this chap came to me and we requested for my 2 Vodafone connections for the port out, he took 1498 as one year prepaid charges and Rs 650 for the 3 months prepaid charges for the other sim
after 4 day when my port out happened, i came to know that he has cheated me and not paid my prepaid money to the airtel.
when i called his he said, ho jayenga?
after rigorous followup he managed for 399 recharge and paid me 800 back for the first sim that too short by 300 . and height is he refused to recharge my other sim, and stating that thats the charges for the recharge .
i expect you all to look and arrange my short fall oe else i need to go to the consumer court
