Sabrina sent you the real invoice on the 4th of July.
The Netgear was not to be activated and should have not been posted in June because it was a small amount.
Anyway, at this point, I would suggest to leave the difference seen that is not that relevant
for the consolidation.
In July you will have to post only the difference between the commercial invoice and the invoice attached (CHF 1’127 – 850 = 277).
Have a great holiday.
