Misleading deals

Misleading advertising... searched for 2 person self catering accommodation, received pop-up notice on screen 'you won entire house for R350' for accommodation advertised as R650 for 4 people, and I accepted offer. Received booking confirmation email. When paying at host I was told it is R350 per person, checking the email I noticed at the bottom of the email it was stated I booked for 1 person. It also stated the cancellation date on date 1 day prior my booking date. Please be aware....
