I have recently changed over to BG Click 6 & opted for paperless billing (my bit to help the planet). They sent me an email to say that my bills were available to view. When I went to the website, I could use "View details" to see individual parts of the bill OK but when I tried "View Statement" to print a full copy, a new window opened but remained blank.. I emailed BG and was told I needed Create Adobe PDF Online which as far as I can see I will have to buy! There is no mention on the BG site of having to purchase a program. I have Adobe 7.0 & Acrobat 5.0 on my system and I can happily open & print bills for telephone, credit card etc.
At least, using paperless billing to save on envelopes & postage helps, even if I print my own copy on scrap paper. A "View Statement" button that does not let you view the statement is surely a worse form of not computing!
