Airtel — sim not working need urgent help

Address:	New Delhi, Delhi, 110033
Website:	www.airtel.in

I am not able to access my number since 2days and after 2days, they are providing me procedure for troubleshoot which i have already done numerous of times instead of resolving it. Service is working from their end but it is showing no service at my end so is the problem resolved?? Secondly i have already been to airtel outlet in morning for sim replacement whereas this is not at all customer fault if sim stops working without any damage and i still paid rs.25 to get it done and its been 14hrs but still end up with no help except no service. I am facing loss financially due to all this. And i have input my sim in different phone as well but still no service is reflecting whereas other sim is showing working in both phones. I am attaching screenshot of no service and will look forward to resolution. I have never came across this thing before with any network so unable to digest how airtel network is sitting quiet on customer problem's and claiming to be best network.
