Airtel — no network inside my home

Address:

Ghaziabad, Uttar Pradesh, 201014

Currently I shift my room in Shakti khand 1 Indirapuram Ghaziabad (very poor network)
I converted it into prepaid to postpaid connection but now I am really frustrated from your network. I am going to port this connection very soon.
I contacted to airtel customer care they told me in foolish manner that your data pack has been expired while I have 102GB remaining data.
Other mobile network is strong like Vodafone and idea I tested in these network so how can you say that we provide smart and fastest network in india.
