Correctly labelled box contained an inferior product

I ordered an Intel NUC Core i5 via Takealot from Laptop Online. What I received though was the sealed and labelled Core i5 box, but inside was an Intel NUC Core i3 device, with a clearly visible Core i3 sticker stuck on on front. The supplier says it was a genuine mix-up between two orders, but the fact is my device was not retrieved and forwarded to me, and I'm the one getting the inferior product, so I've had to now go through the lengthy Takealot return process. Buyers always need to very carefully vet what they actually receive, especially with refurbished products that are not inside a sealed OEM box.

Two stars though for a friendly and quickly response from them via e-mail.
