failed delivery, wrong colour and reneging

I ordered a skateboard for my son. First the delivery did not take place as announced. I was not informed that the driver rejected delivery and therefore I was waiting in vain beyond 5pm. Only once I called @ 17h45 I was informed that the delivery is not even dispatched. When I received the item at the new delivery date, it was the wrong colour. I was informed that this is a 'picking error' and that I can log a return/exchange. I mailed Ms Charles that it is too cumbersome to log a return, that i can't wait for deliveries again and that my son has already used the item. I THEN RECEIVED A CALL FROM MS CHARLES TELLING ME THAT I WILL BE REIMBURSED. I was offered to choose between cash or credit on my takealot account. I chose the account and Ms Charles said I will be informed once the credit is done. There was no mentioning of returning the item. The next day I get another mail telling me that I still have to log a return to be refunded and that I have to return the goods. I do not appreciate this reneging on a promise to be refunded after this disastrous experience.
