Takealot: Reneiging on product as advertised

Can anyone assist me how to escalate my problem, or forward to relevant escalation/legal: Order no: ***7 I ordered 2 x 75ml perfume bottles for R1300. This is exactly what was advertised. I received 30ml bottles for R1300. This is not what was advertised, and not what I ordered. I returned the 30ml bottles, wrapping and seal intact, and requested the correct 75ml bottles as advertised. Over 30 emails and at least 10 phone calls, they now refuse to deliver the correct product, claiming that they made an error on their advert. They have subsequently changed the 75ml price on the website, but I have copies of the advert, the order, the delivery and the return. I believe Im entitled to receive the product as advertised and paid for in the terms of a legal contract. I have escalated to SA consumer complaints: http://www.saconsumercomplaints.co.za/contact/I Anyone have any idea how to take this further? Radio 702? Carte Blanche? Start a social media campaign? Thank you in advance.
