not found 3 phototransistors in Genuino Kit

Excuse me, I am posting by Italy: I have not found 3 phototransistors in Genuino Kit
for the Project n. 04
What can I do?
thanks

Have you identified all the other parts to make sure you are not misidentifying the photo transistors?

If you have then contact the vendor you got the kit off and ask them for a replacement.
