Sneaky survey promotion by Carte Blanche

...at the end of the programme Derick mentioned to viewers to take part in a survey and you could win this Sabi-Sabi holiday, you simply used your DSTV remote control to answer the multiple choice questions, then right at the end on the last frame it says "thank you for taking part" NOW ENTER BY SMSING AT A COST OF R1!!!! there was no mention at all before of paying to enter this! and they have already been given their information for free!! Yes, I know it's only R1 but companies running promotions like this need to be slapped with a fine, simple.
