I notice that there wasn't much of a gap between top and bottom in terms of points. But my experience of Tiscali's Indian call centre, is that it is worse than useless. I don't care whether the staff are university graduates or not, they simply don't understand the most straightforward complaint. And it makes no difference if you speak to them or send an Email.
I was a customer service engineer with BT for over 20 years, I left when computers started telling me what to do, and my few experiences of dealing with what's left of the company since, are sadly very similar to the above.
It's an all too familiar situation with large companies now, try and run them with the absolute minimum of staff, and never give them the time and resources to do their job properly.
O.K. rant over...
