Bharti Airtel — getting 2g speed instead of 4g on the recharge of rs. 399

Address:

Agra, Uttar Pradesh, 282004

My airtel no. Is [protected]. After the offer completion of jio i have chosen airtel for the sake of good speed and charged my sim on[protected] with rs. 399/- offer pack that promises 1gb per day 4g speed data plus unlimited local and std calls...
To my extreme shock i was getting the speed of 2g or equivalent, plus there is a sign of "e" that we used to get with 2g speed...
Sometimes, very rare the 4g symbol is displayed but the speed remains creepy...
I even tried restarting my phone and switching on and off the mobile data but in vain.

Airtel has looted me and i want my money back...
Jio with its slow speed was far far better than this airtel speed... I could easily watch movies without any wait...
The reason i chose airtel is itself foiled by the company... Airtel is fooling people...
