Conditions of order  

Deposit Payments have open refunds as per the terms highlighted above.

The remaining payment to complete final assembly and shipment, will be required within 8-10 weeks of shipment date. If payment is not made in a set timely manner, we presume you no longer want the item, and will incur a majority penalty fee on your deposit refund and may be forfeited.

this is what stands in the original T&O, and besides that you can always ask for a refund based on the DSR rules

please correct me if i'm wrong.
