Many thanks everyone for replies and advise - it is much appreciated!
I accept, and apologize for the fact that I am being frustratingly vague regarding details about the product and the distributor. That's because the only thing I am certain of is that I delivered the Amp in person to the dealer on the 1st February.
I don't want to 'name and shame' at this stage because for all I know there was a delay between him receiving and forwarding the unit, or it could be on its way back to me as I type! Perhaps the distributor is struggling with a health/family issue that is affecting things, etc etc.
Its the lack of communication that I have the biggest gripe with, but as I have so little information to go on I don't whether this is the fault of the Dealer, Distributor or Manufacturer....
The next time I speak with the dealer, if he cannot give me an update then I will tell him that I will contact the distributor directly myself and if they do not respond I will then contact the manufacturer as there is nothing to stop me doing either of these things!
Based upon what other people are saying, any future purchases I make will be determined, not so much by how the product performs, but upon the level of support/customer service the distributer/manufacturer provide....
