Airtel — I am complaining about my airtel number [protected]

Address:

New Delhi, Delhi, 110085

I am naini and i am using [protected] since 3-4 years as a postpaid number.

4 July - I registered a complaint to convert my postpaid number into prepaid number
6 July- I received confirmation via SMS
8-july- I recharged my phone with RS 499, 10, 20 but outgoings were still not working I called up customer care on 121 and 198 but they didn't help me. Since it was a Sunday Airtel store was closed.
9 july- I send someone on my behalf since I was traveling.
11 july- I went to Airtel store they registered my complaint when I ask for solution that lady started shouting on me.
12 july- today also my complaint it not resolved yet.

When everything work is dependent on phone on those days my outgoings are not working.

Airtel customer care is not supporting. Airtel store not supporting.

Who compensate the loss of rs 15000
I have beared just because of my phone was not activated.

Kindly resolve
