I would demand a refund and compensation. I am very particular that either original parts are used or better - and clearly advised in advance of the same.
I agree its a lie and a deception at the owners expense, that was an outcome that suited mr trevor Wilson aka 'zaphod beeblebrox' (as he is also known in other forums) as it was easier for him.
He was constantly trying to convince me to forego my valve preamp project and buy his overpriced ME preamps instead. Unfortunately I found him the most unhelpful and antagonistic person in my diy thread on a diy forum, where he appeared to parade his perceived 'expertise' but refused to actually be helpful in real terms - when asked.
I decided I would avoid him based on this, but now knowing this I would definitely avoid him myself - period.
