Not defending the seller, but as far as Kijiji reviews are concerned, there may be other issues at play. I buy a fair amount of stuff on Kijiji and rarely does a notification come up asking for a review of the transaction. In the last dozen or so, only once. I picked up a couple things this weekend, nada.
Not only that, but few people actually bother with a review in the first place. This is my second Kijiji account (long forgot the info for the first one), I've had it for 8 years and I have 4 reviews from, I'm guessing, 40 or 50 transactions.
