I always tried my best when confronted with people calling with issues and always tried to help others asking me questions as best I could when I was taking tech calls. Sometimes Policy (which I bent more than once!) prevented me, sometimes it was systems or decisions made elsewhere by more senior people that affected individual customers but was 'better' for the company as a whole made it difficult. I did know my stuff but the size of ISP's these days, especially the big ones, means that training isn't the best as there's a demand to get these people onto the phones, the systems are simplified so much that you can follow them and click a few yes/no buttons without knowing the ins and outs of anything to do with an ADSL, FTTC, G.Fast or even FTTP service, you can follow the prompts and click the buttons. Ask a remotely technical query, or have an issue that's outside the norm and you'll flummox most advisors, many of whom are housewives or started work in the evenings for a bit of extra cash doing TV Tech and now find themselves doing Glass, Stream, Sky Q, Sky+HD, Broadband of all types and even Sky GO and Sky.com email support.
