Dear :

I am writing with regard to our order No. which we placed with you on [date] and was scheduled to be delivered on [date]. It is now weeks past the delivery date and we are still waiting for the goods. We are wondering if the order has been overlooked. The delay in delivery is causing us serious problems and we must ask you to complete the order immediately.

Unless we receive the goods within the next days, the order will be cancelled and placed elsewhere. We should remind you that we are holding you to your delivery contract. If any loss results from this late delivery we will be forced to take legal action .

Sincerely yours,

[name]
