Hairfarmer, your thread initially started very well and it was easy to get a handle on your situation.. I was actually on your side. But as your started to say more and it seems like you're ranting on now, I'm kinda on the fence.
It would have be best served if you had documented accurately with high definition photos what you hair was like before, during and after (progressive photos) the HT.
Also please reframe from ranting on about trolls and people trying to shout you down and embellishing your version of events, it does unfortunately make you appear a little unstable, it makes it difficult for forum members to get a handle of your situation. Try to keep it neutral and factual. Generally people can see things for what it is in regards to trolls or whatever.
imo your hairline isn't great, but you did get decent growth. I too would be very unhappy with the results of the hairline if I paid 15-20k for those results. Your situation is fixable, both in regards to your hair and the relationship b/w H&W with regards to refund or whatever your seek in damages.
