Airtel — about 4g services in satara

Address: Satara, Maharashtra, 415002

I am customer of airtel (Satara, maharashtra) mobile no.[protected] from last 6 years.
I have switched to airtel 4g before 5 months.
But i have not able to get 4g services on my handset (Iphone 5s).
I have already registered complaint to airtel customer care but they told that there is no 4g services in your region but my mobile shows 4g network.
Look forward to my complaint else don't make false statement about india's widest network and faster 4g network.
