Wow that doesn't look very ideal at all.
Realistically, what kind of path forward does Hairnightmare have? From the photographs, it appears he might have some keloid formation occurring in the donor area. In brutal honesty, he's probably going to need keloid treatment and a successful HT. Forget the monetary currency, think about the time/emotional investment!
Hairnightmare, you should revisit your pre-operative forms to check for any warnings pertaining to keloid scarring. If there weren't any keloid warnings in writing, requesting for a 100% refund is a perfectly valid course of action.
As Mickey85 pointed out, some of Diep's videos do have some troubling ethical issues (no scar fue claims, 5 minute strip extraction, extracting from NW4 crowns). The doctor's message may seem genuine, but IMO, the evidential cards are stacked against him.
Regardless, I wish you the best in resolving this issue.
