People from India - Which DSL Company do you use? Are you happy with the speed?

I use MTNL's Triband (Broadband). Although the speed is good, customer service is non-existent. If you have problems you have to send an email to their helpdesk. It looks like the email is deleted as never have i got a response from them! Conditions are similar with other service providers also. I also use the service provided by You Telecom as a backup to MTNL. Although the customer service is better than MTNL speed is a issue.
