The quantity and the type of wood delivered to you must correspond to what the merchant specified. For example, if the vendor had promised you 3 cords of wood and delivered only 2, they have not honoured their commitment. If such a situation happens, here is what you can do.
Negotiating with the merchant
Try to reach an agreement with the merchant to obtain the requested quantity or type of firewood. The page Negotiating with a merchant provides tips to do so.
Send a formal notice
If you cannot reach an agreement, you can send a formal notice. The page Sending a formal notice provides further information on this topic.
Taking a case to small claims court
If a merchant does not respond to the request you made in the formal notice, you can resort to the courts. The page on small claims court provides further information on this topic.
