Had to go back to the old system at the moment

If you could go back to the old system (which I presume you mean you've plugged your hub into the old telephone master socket) - and it works, this suggests that your FTTP system hasn't yet been fully turned on, despite the green lights on the ONT.
You're probably best reporting this as a fault using the online system - www.bt.com/exp/engineer-booking.
This avoids having to speak with BT's telephone agents who really only want to upsell you something so they can get their commission, and are not trained in understanding faults.
As an aside, it would have been an Openreach engineer who installed your fibre, not a BT one. But, because of Ofcom requirements, you have to raise all issues with BT as your service provider.

Yes I have gone back to my old master socket which is not turned off yet, should my hub be set at full fibre mode.
Should I change it ,would it change the hub settings and if it didn't work how could I turn it back ?.

It doesn't matter how your hub is set until you change to FTTP. All it does is change port 4 from a LAN port to a WAN port. When you get FTTP, you connect the ONT (optical modem) to port 4.

I have plugged it in port 4 as I was told when I saw 2 green lights on and when I plug it in all 3 lights are green and the hub just flashes pinky / red

Right, if the ONT is green you need to set the Hub to FTTP mode and disconnect the DSL lead.

If your hub was NOT set for Port 4 to be a WAN port (that is for full fibre, Fibre to the Premises, FTTP) then that may be why your hub won't connect when it's plugged into Port 4.
For Fibre to the Cabinet (your old system) it doesn't matter which way Port 4 is configured because it's not used to connect to the Hub.
I would set your Port 4 to WAN (FTTP) mode and try connecting to your hub again.
You can change Port 4 mode back and forth by accessing the Hub manager by typing 192.168.1.254 into a browser on a computer connected to the Hub, and switching "Full Fibre Mode" from "Off" to "On" and vice-versa.
