"Pay Now" Definitely Not Working on myRogers.com

Since August, I have been successfully downloading and paying my Rogers bill online.  As of late last week, this feature is not working, and it is still not working today.

Upon contacting Rogers on the weekend, they asked which browser I was using.  Chrome.  They advised me to use IE.  Well, I'm using a Macbook, so IE is not an option.

They said turn off anti-virus.  Well, there isn't any anti-virus runing on my mac.  In any case, I've been paying my Rogers bill using the Macbook since August.  Other than keep up to date with critical updates, no operating system upgrade. 

I then did try to use on a Windows Vista machine with IE.  Paying the bill online using that machine didn't work either

Then tried on a Windows 8.1 machine, on another network, and did not work either.
[ Yes, I am a bit persistent. ]

So Rogers, here are all the screenshots.

When clicking on any of the "Pay Now" buttons, whether the new red button or the old blue text link in the legacy design, the "???????" window pops up as in:

By the way, it's always 6 question marks.

Here are screenshots from the Windows 8.1 machine, on 3 browsers - IE, Firefox and Chrome.  The browsers are all up to date.  Windows 8.1 is up to date.

Here are screenshots from Macbook with OSX Lion 10.8.5.

 
It would be more convenient not having to go the extra step and log into my online banking account to pay my Rogers bill online, after reviewed my Rogers monthly bill.

That seems to be the way to go for now, or set bill download via ePost.

Rogers, please fix "Pay Now".

Thank you.
