Paytm Mobile Solutions — I want to cancel my order

Hello,
As I ordered kindle paperwhite and recieved a defected piece and request for replacement but at the time of delivery. I will not be able to recieve my packet and none of my family member can. So, kindly refund me my amount. I called Paytm helpline number but there is only auto generated call. I am unable to talk to Customer care officer.
My Order Id is : [protected]
Kindly resolve it and cancel my order asap.
