Tata Indicom Customer Service

In Oct ‘05 I got a broadband internet connection (prepaid) from Tata Indicom.Before that I was having a dial up connection(prepaid) from Tata Indicom with user ID vasanthu@eth.net. I was assured more than once by Tata Indicom Customer Service both over the phone and by e mail that my unutilised balance of nearly Rs 1000 in my dial up account would be carried forward to my new broadband account though my user ID will be changed to vasanthu@vsnl.net. But after I actually got the broadband connection they told me that my previous balance with eth.net ID cannot be carried forward. Inspite of my sending several e mails to Tata Indicom Customer service drawing their attention to their earlier assurances, I am getting only expressions of regret and vague assurances that my concern is being looked into by their resolution team. Till date nothing has been done to settle my complaint and no final reply has been given.In the meantime my attempts to utilise the previous balance with eth.net id to download music is also not bearing fruit as whenever I try to log in using my eth.net id I get an error message “invalid user name” though the download site has provision for using eth.net id. My complaints in this regard also have elicited no response.S.Gurumurthy
