Back up your accusations with your identity.
Show all this proof you claim to have.
Prove you did business with me and have any knowledge of my customer satisfaction. The customer you used as an example posted back about the experience so that should tell you something - you're angry about it and he's not.
LOL.
don't let this ignorant person ruin your day, your customer spoke to his experience, any reasonable person should see who is being honest here.
