Subject: Formal notice to start the work
Dear Sir/Madam,
We signed an estimate together on [indicate the date the estimate was signed] for work concerning [indicate the nature of the work]. You were supposed to begin this work on [indicate the scheduled start date]. However, despite my many phone reminders, you did not show up and did not inform me.
I find this behaviour particularly inappropriate. Please note that I had to take time off work to wait for you. Consequently, I hereby formally require you to start the work within eight days of receiving this letter. Without any response from you, I will be forced to request a mandatory performance order.
Awaiting your reply, please accept, Sir/Madam, the expression of my distinguished regards.
