Airtel — network problem in the area

I m a customer of airtel since last seven years. Now I'm serving in Hyderabad (near golconda fort area). Here in this location the whole community is facing network problems. As I have 4G handset with 4G SIM but never get more than 2G connectivity which is also occasionally. The experience here with Airtel is worsed and forcing me to leave your services. The matter reported twice to customer care but go in vein. Please have a look on the issue and take action promptly. Since it's a matter of pride for a company which is one of the bests in the field of mob sector. Keep in mind it's happening in Metropolitan city like Hyderabad than imagine but will the conditions in other areas.
