No Internet On Activation Day

[#1]

Today is the day my fibre should go live. Its nearly 8pm and ive still not got internet. Router shows orange bar and a red b on it. Spoke to someone twice today and they said it could take up till midnight to be on and its down to the openreach engineer.
Well i spoke to an openreach engineer and he said its not down to us because all youve done is move provider its not a new line. The phone line was still there all thats happened is youve gone from one provider to another. It should be on and thats down to plusnet.

So can someone tell me whats going on properly please.

There’s more to an activation than engineering work. I believe an order would need to complete on several Openreach systems which can take up to midnight to happen.

Still the same. Not connected when should be.
