Sydney Sheet Metal

I am so disappointed with this company. I e-mailed two very clear diagrams for the sole purpose of having them (Alan) assess my requirements.
Hi Alan
Attached info for
Two story timber home
Flue requirements.
PDF 1 (drawing) clearly shows the height of wall and degree of roof (I am a trade certified carpenter in regards to my ability to draw an accurate description of what I require)
The product was fine, the problem was Alan had sold me three flue lengths too many.
I called Alan to arrange a return, Alan informed me that he did not take back any returns, I stood my ground and made it clear to Alan that what I received was based on his calculations, at first Alan accepted this then decided he needed to speak with his partner which resulted in a 50% return payment offer (paid $120 which was a good price to be fair). Again I stood my ground which resulted with Alan transforming from the very nice affable guy to " I have given you my offer, if that's not good enough I don't need you wasting my time, my reply "don't worry it’s not worth the insult".
Good product
Good price
No ethics if there is an issue.
