Consumer Redressal

Suddenly a day my Aircel no.(7098877271) has stopped working and displaying that sim registration failed. When asked to the executive he replied to resubmit the documents as verification has been mismatched. I replied nothing and mailed a complaint to the higher authority on 31st may, 2015 but on 3rd of this month he gave me the same option in a reply mail. Then on the same day I replied too him that why should I resubmit my documents as the connection has been started by proper verification of the documents and now you are saying that it has been mismatched. I also mentioned that if he surrender me my old document with a proper reason as it is your fault then I will resubmit my documents but still now no reply has been given to me. So, at last I am at your door for justice as the appellate authority has been harassing me for the past one week and not starting my connection. As it is company's fault then why should I'll be the victim?? Pls help me. Regards Sujit
