Airtel — Deactivated my Sim for 3 days without a proper response

Address:

Bangalore, Karnataka

I recently went to Airtel Relationship center ( Branch Rammurthy Nagar, beside Mega Mart, Bangalore) to convert my prepaid to Postpaid connection. I raised a request on 31st July and waited for 3 days to get the sim activated. I went to their store on 5th August 2015 and they said that it will be done within 2 hours and I waited for a day and on Friday 7th August 2PM I lost my connection. Neither of Postpaid and prepaid sim are activated. I tried calling the Store and they were not responding. Worst thing happened on saturday they made me come to their store for 4 times each time promising me that it will be done within 2 hours. THis is the worst service that I never expected from airtel. The store gave their contact number and one of their representatives number also but no one will respond. My sim is not activated even now. I am still not able to make any calls or not receive any and customer care are telling that it will be done within 4 hours from the past 12 hours. I am fed up with the service and want to migrate to other provider once the number gets activated. Worst Worst service ever and work Airtel relationship service center ever.
