So I saw an ad with something on Kijiji Ottawa that I wanted and checked the location. The Kijiji postcode showed that the seller's location was right downtown and easy reach by walking so I contacted him and made an offer.
When we agreed and I asked for his address, he gave me somewhere way down south of the city as his address which would have meant a much longer journey. I told him I was not happy with this and he then gave me a location in Renfrew to pick up or give him $10 to drop it off. I explained to him that I made the offer to buy based on his apparent close location and I really didn't want to travel that far or give him $10. He told me "no worry" and we parted amicably.
The next thing I know is that he gave me a negative review as someone who didn't show up and it was too late for me to respond. The fact that he has the wrong location in Kijiji (and he still has it, weeks later) suggests to me that HE is the one who needs the negative review but now I have no way to get this rescinded.
