Refuse to except return

I brought a Carmen stand hair dryer. When I received the dryer only had one foot instead of 5. Takealot says return policies states return within 7 working days (which excludes) weekends. When I returned the product they said I failed to return within 7 days (they included the weekend days) which I have not if you exclude the weekend. So now they taking forever to send me back a stand dryer which I will need to try and fix. I learned my lesson from purchasing from them consultants are terrible with attitude problems and no one cares because they already sold a broken item so what do they care
