Airtel — no 4g data speed and no network coverage sometimes

Address: Udaipur, Rajasthan, 313001

There is no 4g data speed as airtel brags about as i have been experiencing problems since the day i have recharged my phone
Why does they give you fake promises if they can't even fulfill it
And there costumer service is soo poor that when i tried getting help from there they said they regret regarding my problem but have no solution towards it
It just as simple as that i want my money back with an apology from airtel regarding their disrespect and fake promises.
