My network automatically get converted to 3g or even 2g from 4g...
The speed decreases too much...
I have already complained more than 5 times for this issue.. Bt every time i call they will say dt we will resolve in 6 hours or 24 hrs or bla bla.. Bt still its been 2 weeks n my problem is not resolved...
The company is ignoring it from a long time..
Please take strict actions and resolve my matter asap
