[Resolved]  Airtel — sim not activated even after 34 hours

I had lost my phone and immediately blocked my airtel sim card. I went to airtel store on saturday 2nd september 2017, and took a new sim card by showing my aadhar card. I was promised that line would be activated by 4 hours. When i inserted the sim after 5 hours, it was showing sim card registration failure. On contacting customer care, i was informed nothing can be done i need to walk in at relationship center from i bought the card needs. Visited said nothing can be done from their side it is backend issue. Everything would be seen after monday. When it comes to payment sms are send reminding us the due amount is pending, for service issue no one is responsible, worst pathetic service from a company.
