The worst online shopping experience

The worst customer service in south Africa. I ordered 24 cans of happy juice. After using some, I decided to unpack the rest. I called takealot for assistance. Firstly I was told to go purchase again the cans I used so I could return all 24, then I was told that I can return the used up cans with the rest of the damaged and unused and that theres no guarantee that my return will be approved for a replacement. His exact words was that once my return is received the manufacturer and warehouse will investigate and if it is denied then I will have to pay for a replacement. Then why the hell must I send my cans back if there's guarantee that the issue will be resolved. This is not acceptable for a consumable item. The manager I spoke to was Laurence. He was unhelpful. I will never order from this poor excuse of an online store. I have used takealot in the past. The order might have been small, but If this is the way that takealot treats their customers, that's the reason why they would never even grow to a fraction of amazon. Better customer service always brings in more business. They need to look into the return policies.
