Unwilling to exchange incorrect product delivered

I have bought many items via takealot and have always been happy, until now. I bought a Skybell HD for a present. On the website and on the takealot sticker on the box it showed Skybell HD, but when it was opened it was actually a Skybell 2 which is the older versions that does not have the functions I need and is the less expensive version. I thus paid the increased price for an inferior product that cannot do what I need. I tried to exchange it for the correct product, but because 30 days have expired between purchase and delivery, they said I could not be helped. This is clearly false advertising and *****ing and no matter what their Policy says they should replace it as long as it is within the 6 month period guaranteed by the Consumer Protection Act. Extremely unsatisfied.
