Airtel Postpaid — blocked the sim

Address:

Chennai, Tamil Nadu

hi, i am sivakumar my no is [protected]. i got a call from the postal to drop my bill but i have changed my address from their so i said them to drop it in my sister address for that month only. But by mistake they had changed my address to my sister address in which i dont have any ID proof. Now they blocked my sim for not submitting address proof from my sister address. Now i gave them a new address proof for my change of address but they r not accepting it. first they want me to give a address proof for my sister address which i dont have on my name.
