I had the opposite experience a few months ago. I was calling to change a flight. I called the gold line, but was connected to the indian call centre. The agent was very friendly, and when discussing the fare rules and different dates and prices (that I had looked up beforehand), he asked me where I got some of my information from. I mentioned google flights, but then he said 'Have you heard of flyertalk?'. I said yes, and he mentioned he visits almost every day and has learnt a lot from here, and that he loves the site.
