Airtel — postpaid service stop

Address:

Pune, Maharashtra, 411044

I am using airtel ([protected]) postpaid connection last three months and yesterday my no suddenly stop. I called customer care executive for this issue they told me your address verification pending and suggest me to go airtel store with current address proof and continue your service.

Now i visited airtel store (Baner, pune, maharastra) she told me your maximum (3 times) verification failed so you can only convert this sim to prepaid. If you want prepaid then i can help to convert this no to prepaid otherwise i dont have authority to start or continue.

So my basic question for airtel is what is this i already paid all bill on time then how can stop my number if address document (Verification) is not safisufficient then why started my no in airtel.

Note : no one contact me for this address verification pending part before stop.
