In many cases, product manufacturers do not provide retailers with options for resolving missing components. We recommend that you start by reaching out to the board game publisher - many publishers have a missing component claim form on their website that you can fill out to get replacements shipped to you directly.
If you have already contacted the publisher and have not received a response within a week, please feel free to email us at info@boardgames.ca, and we would be happy to see if there are any options we can take through our distributors to get the problem resolved for you.
