ATG Stores ATG Lighting Universe Wrong items delivered - no refund and no response from customer service, Internet

I ordered lighting to replace all lights around my house in December 2011. An additional order was placed the same month. The first order was completed correctly. The second was misspacked and instead of lighting contained plumbing equipment. 

I am Canadian and sent an employee to pick up the shipments from their reception point in Vermont. The border guards then determined that there was a fraud attempt, i.e. of passing equipment into the country that were not supported on the papers presented for inspection (papers presesented were the bills received from ATG). As a result, the equipment has remained at Customs, I was charged more than $150 for fraud with a mark against my name for 5 years, and am still without the equipment though it was paid for (at the cost of hundreds of dollars). 

I kept in close contact with Customer Service during the episode at the border, by phone and e-mail. ATG Stores also contacted Customs directly, cc to me, confirming that the mistake was theirs.

After that, to finalize the order and get the remaining pieces, no news. Despite follow up, still no response.
