I have taken this go999 connection

I have taken this go999 connection ,the connection came up in a week but it only has worked for 15 mins.The configuration done intially was for post paid but from helpless desk I came to know that prepaid connection requires a different configuration . from that day i.e. from 1 st july till date it is still not working .I have done a smart thing of going to site www.vsnl.com , I went to the list of board of directors , i took all their names and mailed to all my issues by adding a full stop between their name and vsnl.co.in as the address . Which has worked as none of the mail has bounced back
