Yahoo! Mail support is a joke

For some reason, lately when I go to Yahoo! Mail (mail.yahoo.com), occasionally instead of going to my inbox, I get a page of raw PHP. Here are the first few lines:

<&#63;PHP
ini_set('display_errors', 0);
$data = yahoo_reg_login_setup();

if ( $data === FALSE )
{
    exit();
}
else if ( ! isset( $data['DISPLAY_FORM'] ) )
{
    error_log( "yahoo_reg_login_setup didn't set the DISPLAY_FORM field" );
    header( "Location: http://login.yahoo.com/");
    exit();
}

Here is the rest of the PHP code. It is obviously the PHP code that runs the base of Yahoo! Mail, which decides where to forward you: either to your inbox or to a login page. At any rate, there's no reason why Yahoo! Mail's servers should be sending me raw PHP.

When I get this page, if I hit 'refresh' I'll get the correct page, so things aren't totally broken. This slightly annoying, and it's obviously a problem with Yahoo! Mail's servers. My web browser is incapable of producing raw PHP code, much less with a Yahoo! Mail bug tracking number (see the full text).

Trying to be proactive, I sent this code to their help department. I also wrote "Please don't tell me it's my problem, as there is no way my browser can generate raw PHP." They wrote back telling me:

We understand that you're receiving a HTML error message in your account ... To help us troubleshoot and assess the issue, please take a screenshot of the entire page when the issue occurs next.

They then proceed with instructions on how to take screenshots in Windows. As a Mac OS X user, I found this help insulting and useless. I am no common Windows user, and they shouldn't assume I am. Furthermore, providing a screenshot is even less helpful than my original post, as the PHP code covers more than one contiguous window - I have to scroll to see all the PHP code. It's clear that either my message wasn't read, or the person reading it had no idea what I was saying and put in the most general pre-written reply they could find.

It says something about your company when this kind of 'help' is allowed. This person should have forwarded my message to someone who had a clue. They shouldn't have sent me anything, much less nonsense, when they no idea what I was writing about. Perhaps there is no conduit for this kind of thing between the Yahoo! Mail help staff and the actual programmers. If that's the case, it's a shame, and it's more evidence why Google is kicking Yahoo's butt.
