It looks like there's something wrong with your order I'm afraid - part of it is stuck, and Netflix is missing from it completely. I would recommend you call the helpdesk so that they can raise it again.
There's a chance that our offline team will pick up on the error and fix it automatically, but I cannot guarantee if/when that will happen.
Your other option is to use the Join option in the Netflix app specifically on the TV Box you should have received. Doing it there will specifically add it to your EE bill, which should then automatically not be charged due to it being included in your subscription. Make sure you select the Standard with Ads option to avoid being charged extra.
