Airtel — fraud sales call

Address:	Lucknow, Uttar Pradesh, 226016
Website:	Airtel.in

Problem:
I had recently been called by airtel's customer care exactly 3 months back offering to port my mobile number from tata docomo (+91-[protected]) operator to airtel as tata docomo is shutting down (As i've been told).
I had been mislead that if i switch my network to airtel, only porting to postpaid is possible and i can switch to prepaid account after 4 months.

The fix airtel provided :
