yes you press on the word tiklayiniz after it says 'fatura gormek icin' then you get a little screen where you put the number you see in the little box and then press 'goruntulu' - then if your pc does not get hiccups as mine often does at this stage (think the virus programme does a double take) you will get the bill in a seperate screen on some reader thing whose name I cannot remember-acrobat? - where you can read it but not save the details on it as the pc (well mine anyway) cannot verify the source, but it does have all the details.
Do make sure you press on the first 'tiklayiniz' on the email as the one at the bottom is for looking at the back page of the bill!!???
