What do you do in this case:- Bought expensive product and it was very poor quality. (Heroin #4, 1/2 g for $240.)- Already Finalized thinking it was all good at first glance until I tried it.- Sent vendor msg asking what is up with the poor product that almost poisoned me?. No replies for days. - Was angry with vendor so I left a 1/5 rating and wrote the truth in the feedback field- Vendor wrote back with threatening words that I better change it or else, that he would tell all other vendors to blacklist me.- I never asked for a refund, only a better product on my next order. I asked if we could resolve the issue on the next order. Vendor said no. No resolutions. Change the rating or else suffer the consequences!- I was too scared to get banned or ruin my great buyer record. I didn't want my next order of heroin to poison me or anything like that..- I changed it to a 4/5 in fear of any consequences. I also deleted the truthful feedback and wrote a lie . Good vendor great product..as if.. .What went wrong here?I still got ripped off. (I bought 1/2 g of heroin for $240. and it was all cut. It burned in my veins and clogged the syringe and I had to toss the rest in fear of what it really might be)No resolution and threatened. Again, I use IV drugs so I'm fearful someone will do something stupid on my next order. I'm afraid to write truthful bad reviews for fear of retaliation from the vendor. The Vendor forum could be used to get back at a buyer for writing a bad, but truthful review.I've been selectively scammed by a huge and reputable vendor as well. I felt soooo dirty writing the feedback 5/5 good vendor. In reality, the package of MDMA I ordered came as a white powder that tasted like icing sugar. In fact, it was. (Sigh) I wrote to the vendor and explained, the vendor said "All my reviews are great. You are the only one complaining. . " He was right. So I bit the cost and wrote a positive review, just so I don't get blacklisted or upset the few domestic vendors I have to choose from There aren't many domestic vendors in Canada to start being picky-choosy, so I have to take the abuse... sadly.There must be a better way?
