Airtel — data network problem from a long time and no action is taken despite of many complaints

Address:

Jalandhar, Punjab, 144411

I am using two airtel numbers, one from 2 yrs and one from 1 year. Though i am a 4g customer i get a maximum data speed of 1.5 mbps that too at late night which results in poor downloading speed. most part of my data pack is wasted accordingly.Coming to calls, everytime i call someone either it does not connect or if connects, nothing is hearable in the first call. Again i need to call nd talk. I have tried many modes of complaints but it has never worked. I request the authorised person to consider my complaint as i have no other way left than leaving airtel networking service.
THANK YOU.../
