Have not received Optical Network Unit

Hi there, 
A technician installed optical fibre to my house 2 weeks ago, and I have received the router.
However, I haven’t received ONU (Optical Network Unit) and cannot connect the fibre and the router.

Asked customer service to send it on Friday 5th August, and he said it would be delivered on 6th.
However, I haven’t received it, and my questions are, 

1. Has the ONU been arranged to deliver?
2. If so, when do I receive it?
3. if not yet, please arrange the delivery asap

 The internet fees' charged from August and the house is missing the internet connection, I need to solve the issue asap.
