Paytm Mobile Solutions — Paytm postpaid account not closed and still getting calls for recovery after making the payment

I have used 1500 rs from paytm postpaid. my bill due got upto 9000 after I got a call and they said ypu have to pay 2000 rs and remaining amount we will wave off so paid 2000 rs but again in last month i got a call and they said you have paid the principle amount but your due amount is pending so now you pay 1000rs and we will send you closure mail and close your account so again I paid 1000 rs but still my account is not closed and I am getting calls for recovery and they are harassing me so I request you to please close my account as I paid 3000 rs for principle amount of 1500 rs and still getting calls and massages for recovery this is not acceptable from a reputed company like a paytm its seems like a scam. please assist my complaint and resolved this issue ASAP.
