Here in the UK you would deal with your dealer. It is with him that you have the contract. Even if they no longer dealt with their distributor or manufacturer. It is with the dealer you made the contract.
I am sure that in your neck of the woods, similar laws apply. Take the board to your dealer and tell them to sort it or you want your hard earned back, simple as that. Not really much point coming on a forum to vent your spleen, or do you think that will make your dealer work harder? I doubt it.
