Don’t purchase books from Takealot, they send damaged and won’t replace

I purchased a French dictionary from Takealot. It arrived very damaged and despite sending them proof of the damage, they are refusing to refund or replace the book. I understand books are non-returnable as you can read and send back but this book is a dictionary, and the damage is clear. I took it out the plastic and saw it as that. I purchased it as a Christmas gift and cannot possibly give it to my mother now. Why as a consumer should I carry the cost of them sending me a poor quality book? As they are an online store I was not able to see the damage before purchase and I let them know as soon as I opened and saw it. Their website also states if the item is delivered damaged it is returnable.
