Takealot false advertising...

So I bought some Canon ink cartridges, https://www.takealot.com/canon-480-xlb-481xlc-m-y-ink-combo/PLID***7 says Canon in Description of item, in Product Information section it states Brand is Canon but when the item arrived its a knockoff brand, wanted to return it unopened, but Takealot says the item is non returnable!
