O'reilly Arrogance ?

A week ago. I tried to register for the Python Programming Certificate on the O'Reilly School Of Technology website. There appeared to be a glitch and I saw the following error message :


It seems there was a glitch on our end. Please report this error to us at support@oreillyschool.com, and if possible include your browser and operating system so that we can determine the problem. We sincerely apologize for this inconvenience.

I sent an email to the suggested email address with all required information. 4 days later - no answer from O'reilly support. Just yesterday I sent in another request using their "Contact Us:" web form. No response yet.

This leads me to worry. Even unscrupulous businesses would take your money first and show their unprofessional ism later . With O'reilly it seems they don't want my business. Should I feel comfortable about plunking down hundreds of bucks on a set of courses from an institute that does not take the trouble to get me correctly signed up first ?

If this is how they behave up front, how could I possibly expect professional technical support later while actually taking the classes ? Is this what one ought to expect from O'reilly or is it just me ?

Thanks,
