Hello reddit I am a DMN vendor with a solid reputation and product. Current I have a customer claim my product bunk or some other chemical and is demanding a refund or other product instead. The product in question is not a new item dozens of others have used this same batch and have no issues. They are now threatening to leave negative feedback if I do not reship him product to his satisfaction. I feel this is kind of extortion on his part what does reddit think?
