Fair enough, @Lester, and thanks for your help. Interestingly, I came to this neighbourhood at the suggestion of AGL, when they responded to my 1-star review describing my issue. They also told me that this was how they could provide the stellar customer service that they were desperate to give me. So, I had a look and saw that they did seem to respond to problems raised here. Maybe I'm the exception, or maybe I'm already getting the customer service experience that I deserve. Well done, @Leste ...
