Airtel — For Sim Replacement

Amarpur,Mednichowki,Lakhisarai

Dear Sir/Ma'am
My name is- Badal Kumar

Contact No.[protected]

My concern is that my airtel sim today by itself is not working so for duplicate/replacement sim I had visited 2 airtel store in my nearby with proper document but they said that we charge Rs 150 for the same.
Is this service is chargeable ? I don't think so.

So, please help me regarding this and take necessary action on it.
This will I'm very glad to you.

Thanks & Regards,
Badal
