Airtel — complaint regarding sim.

Address: New Delhi, Delhi, 110002

Sir i am purvesh pandey, regular user of airtel services.
But this time my experience in airtel store was worse. I had lost my prepaid sim, so i went to airtel store in dariyaganj to get a new sim but without my confirmation the executives there, alloted me a postpaid sim although i had told them to give me a prepaid sim.
So i am requesting you to help me and solve my problem as soon as possible.
Otherwise i will have to port my sim card to jio.

Thank you
Purvesh pandey.
