Airtel — not working 3g internet at daytime

Address:

Lucknow, Uttar Pradesh, 226005

Hello i am using airtel from past 4 years never faced such problem, from past 2 weeks i am not able to access internet during daytime.in my phone it shows that internet is connected but the net doesn't works. Despite regular complaints at airtel my problem is still not solved and still faceing the same problem. Despite having 2 gb regular daily data i am not able to access it. Ironically it works only at night 1-5 am. I am literally unsatisfied with this network. - saumya
