Hi you should email them, raise a ticket and consider phoning them.
I do not advocate voicing concerns about a company in a public forum until all these routes are exhausted.
Ordinarily, I would jump to the defence of AmigaKit as my purchases have always gone smoothly.
BUT
I attended the Amiga North Thames show in December 2009. I left my Scandoubler with Matthew as it had a fault.
Now in March 2011, after numerous phone calls throughout 2010 and emails in 2011 I am STILL awaiting a diagnosis...
I know that my Scandoubler is small beer to Amigakit, but these "small" things are significant to me and my future buying habits.
