If you follow the above instructions you can find a customer service number easily from the manufacturers site. The manufacturer has already been mentioned earlier.

I must say that from the customer reviews at Amazon I noticed two things - firstly it does sound like an amazing product - it reminds me of the 'Young Ladies Interactive Primer' from Neal Stephenson's 'Diamond Age' - something I thought was completely science fiction until now.

Secondly, while it is much easier to complain about something not working than it is to rave about it working okay, there does seem to be a few problems with it. Having to return 3 of them seems excessive.
