Consumer Redressal

I am a TCS employee and I had applied for a corporate Airtel postpaid connection through your representative(Mr. Sunil Prasad, mob: 9903975010) who was representating Airtel in our office(Delta Park Lords,TCS,Sec-V,Saltlake) . I wanted to change my number(9007973173) from Tata Docomo to Airtel and thus applied for the connection on 04.09.2014 and the representaive assured me that the connection will be activated within 5 days. However, it is now the 14th day after applying for the connection.Moreover, My Tata Docomo number is also deactivated for the last 5 days in this course of porting and thus,people are unable to contact with me as this is my official number(9007973173). When I am calling Mr. Sunil Prasad(Sales Executive),he is assuring me that the connection will be active within the same day,and this event is happening for last 1 week.Recently,he has also stopped picking up my calls,and even not replying of the requesting SMS,which I am sending to know the status of the request.
