JB Traintours to be avoided

I booked and paid for a tour only to be informed the next day that the tour was fully booked and was promised that my money would be refunded, Subsequently i received emails from them where the same"full" tour was advertised ????Now almost 2 weeks later and after numerous phone calls and listening to sweet promises there is still no sign of a refund in my account. The question to be asked is if they are advertising tours that are already full to get payment and keep stalling the refund on purpose or is it simple bad management and administration?
