You asked earlier on in the year about fibreoptic. I was the one who answered your question. All you can do is wait. There are always blockages in ducts and BT do take their time to unblock all of them. But I suspect that you should get fibre at your given date because i dont see any Openreach unbloacking ducts roadworks in your area. Think about me, I have to wait a whole year for Fibre and they might be giving me a rubbish date aswell.
All you can do is be patient
