I've been with TT for years now and yes they can be awkward and reluctant to handle stuff correctly, however 99% of the time it works and in my experience the actual problems needing to be fixed are actually down to BTOR and TTs reluctance to get them involved. I have only had one real issue in the past years which was an actual problem with the TT network. Everything else can be placed firmly in the BTOR court and their 18th century equipment.
