Consumer Redressal

From 22/06/2015 morning, 0600 am (i checked) my airtel sim is not working. I have got a new sim on 22/06/15 at 0315 pm but the same even has not been activated so far. its been more than 30 hours and i am unable to access my phone to make and receive calls. I tried calling airtel 4-5 times but so far have not received any concrete response from them as why my old sim has stopped working and why my new sim has not even got activated, wherein i have been told the sim will be active in 2-4 hours but it is close to 24 hours now. I am really frustated now as i can't port my number to different operator till the time i don't send sms from my current working number for portability (as told by customer care from airtel). I am helpless as everytime they have not respected the deadline provided by them to resolve my query. My work is suffering as the basic contact tool my mobile number which i am using from last more than 12 years is not operating. looking for Consumer redressal forum support
