Answered question
Is there a way I can get my monthly bill in a pdf format via email?
That's not a feature that is currently available unfortunately. Definitely need to add it to the wish list. You will have to manually go into My Plans> Transaction History and take a screen shot or print to a pdf file and save it. On the bright side, they have made the receipt clearer with detailed information now.

As mentioned by Kenny, it is not possible for now. You need to log into your account and download manually.
Thank you very much guys
