Neither are you, Edward. So I guess what's good for the goose is good for the gander, to quote an old saying. You call your clients liars when they come to this forum to post complaints, yet you are quick to throw a fit about those same clients if they say the same thing about your company. Interesting customer service tactic.
Saying "I'm sorry about your experience - what can I do to help?" or offering something other than defensive, repetitive speeech, accusations and challenges might be more helpful. But somehow, I don't think you're interested in that.
