Very worst connection. Review on Airtel Broadband

By using airtel mobile office connection, we have to bear heavy loss of time rather than money also it brings the highest tension to the customers. I request airtel to upgrade the speed of mobile office. I also request all mobile office users to place such comments to make alert the airtel. There is not at all enough speed to browse the internet: having this in one side, I have to protect my system from virus, and for that I am trying to download an antivirus program for the past two years, but still I cant download it. I dont know what is the aim of providing this service. Airtel has to explain. I have been complaining about the speed ot the airtel mobile office connection. But they still deny that my handset is having problem. I would like to make a clarification. Is nokia n70 is an advanced set or not? If not why airtel cant manufacture a handset for using mobile office connection. Thousands and millions of customers are suffering by using this connection. Even I am trying to post this review for 4 times. Because for three times, the connection hanged and disconnected. I think no other example is necessary to explain the speed of airtel mobile office.
