Airtel — 4g data stopped in area from last few days

Address:

Kota, Rajasthan, 324008

From last few days 4g data service has been stopped in area (Kunhadi kota rajastha -324008). It was working fine till 27 sept after that something happened and nobody in area is able to access 4g data though airtel has already charged 399 for 70 days plan (1gb data per day). Please get this fixed as soon as possible because it disturbing my work. No good response from customer care calls because they always say that they will send this further forward but don’t tell about what has been done in last 4-5 days? What problem found and what are they going to fix? If they can not answer these questions that means nothing they are doing about it
