A Girl's World Productions Inc

I purchased the babysitting class online with credit card and entered email address as required. An email was supposed to be sent with registration#, password to log onto the site and take the course. No email has been received and my credit card has been charged. I have contacted the company by phone 4 times and left messages to call me back. There has been no return call. I sent an email to customer service requesting the registration # and password but no reply has been received. I don't understand how a business works without a functioning phone #. All it says is "your party is not available at this time, please leave a message." I have called at different times during the day and evening.
