Hello Norman
sorry to hear about the difficulties you're experiencing.
I don't know much about them but what I can tell you they advertise on many national magazines, appear to be a serious dealer and i honestly havent heard anything negative on them.
What I can suggest you, if you like, you can send me more details (dates, order numbers, invoice etc) in private and I can draw down a clear letter for you to send them and see what happens next. I could even give them a call directly as a last resourt and try to put some salt on theyr tails.
Ciao
E,
