Airtel — pathetic voice quality

Address:

560037

Hello,

I have raised complaint twice this month, Following are the complaint numbers:
COUTL[protected] - on 7th april, 2018
COUTL[protected] - on 12th april, 2018

against pathetic voice quality and i cant even understand what the other person is speaking. I have raised complaint twice and some temporary fix happens after one day and today (17th april, 2018) the problem is back.

I am frustrated on how many times i have to call airtel and report this issue.
I stay in yemlur area in bangalore and my number is [protected].

Didnt expect such a thing from airtel or should i migrate to other vendor.
This problem started from VOLTE and i dont understand i cant even make a call if i switch off VOLTE in mobile.

Thanks,
Sreekanth
