Takealot — progressive kitchenware - microwave fish and vegetable steamer - transparent

I bought this Microwave Fish and Vegetable Steamer from Takealot the other day and after my 3rd use, it completely melted and deformed the lid. (attached is a picture)

I've tried to rate the product on Takealot but my bad rating was never published. I tried rating it again but then received an error stating that I've already rated the product and cannot rate it again.

I also tried contacting Takealot directly but cannot seem to find any email or contact information for them to do so.

I am honestly very disappointed. I've bought products from Takealot before and I was very satisfied in the past. I expected more from this product.
