According to Fair Trade act though there is a section "Buyer's right of examining the goods" it says......
Sec1 "When goods are delivered to the buyer, which the buyer has not previosly examined, the buyer is not deemed to have accepted them unless and until the buyer has had resonable opportunity of examining them for the purpose of ascertaining wether they are in conformity with the contract"
Sec2 "Unless otherwise agreed, when the seller tenders delivery of goods to the buyer, the seller is bound, on request, to afford the buyer a resonable opportunity of examining the goods for the purpose of ascertaining whether they are in comformity with the contract"
A contract is between the buyer and sell written or verbal, the contract was not fulfilled so I can legally request a refund since he is a registered business and if he doesn't want to then I can goto small claims and good chance I will win since half of what I ordered is missing and other half is not to my design needs as required by our contract.
